Organic Chemistry

Hi Everyone, I'm trying to confirm a synthesis of an amide. I ran an IR and I have a peak at 1641 and 1562 cm-1, so I'm assuming it's a secondary amine. I wanted to know if there were any chemical tests I could run to confirm the presence of an amide? I only remember amine tests from organic (Hinsberg, Acetyl Chloride, etc)... I have very limited amounts of solution (15 mL), so I can't afford to run experiments that give false positives or false negatives. Can anyone suggest any tests?

Hello All, Fullerene study has always been a hot topic surrounded by scientists. Research in carbon fullerenes has lead to many new inventions like superconductivity, fabric makeup, etc. Scientists are frequently searching for more ways to equipment this carbon formation.

Hello. Can someone please help me with these organic chemistry lab questions? Thanks in advance. Here's the reaction: 4-Chlorobenzaldehyde + KOH,H+ >> 4-Chlorobenzyl alcohol + 4-Chlorobenzoic acid Purpose: This experiment illustrates the simultaneous oxidation and reduction of an aromatic aldehyde to form the corresponding benzoic acid and benzoyl alcohol. 1. In this experiment, the alkaline phase was diluted with water. Then it was acidified by concentrated hydrochloric acid. Discuss the acidification of the alkaline phase. How does it help in the isolation of the carboxylic acid product? Use an equation to help explain this point. 2. Think…

I was looking into this chemical for a project for myself, and I'm afraid I can't find much info on it. What are some of the dangers in this chemical, storage properties and the status of it being watched. It'd be hard to explain why I have loads of NaOH and LiOH in my garage. Even though I'm a ligament soap maker.

Hi friends How could one determine the pH of a non aqueous solution. i.e. solution made in organic solvents plz suggest

Hello All Member, Is fullerene a class of carbon molecules? Please share your suggestion here. Thanks in Advance..

Hi. I was wondering if someone can show me the synthesis of butyl isopropyl sulfide using 1-butanol, 2-propanol and any solvents/reagents. I tried treating 1-butanol with SOCl2 to form chlorobutane and 2-propanol with SOCl2 as well. I'm unclear onto how to get the sulfur connected to those 2 parts. I assume when that is accomplished, Mg in solvent can be used. Oxidizing agents like KMnO4 can be used and Zn(Hg), HCl as a reducing agent to remove the carbonyl at the end.. Any help is greatly appreciated!

what would happen if imidazole acted as an acid to react with Ch3MgBr (a base). im not too sure how this acid base rxn would go further?

I've been reading about toluene, and I understand the distinction between dry and wet toluene. However, I was wondering how much water toluene actually absorbs, and if it is really important to have dry toluene for general chemistry. If it is absolutely critical what is the easiest way to dry toluene?

ok sorry for all these questions but i really can't predict the right answer. say you were to mix methane and chlorophenol in a 1:1 ratio by molecules, would you get hydroxytoluene + hydrogen chloride or chlorotoluene + water? what if instead of chlorophenol it was chloroiodobenzene? would you get chlorotoluene + HI, or iodotoluene + HCl? i would think the latter but i can't say for sure.

ok so lets say this is methyl: R-CH3 and this is ethyl: R-CH2(CH3) then what is this? R-CH(CH3)(CH3) idk if you can imagine it, its like a methyl group, with two of the hydrogens replaced by methyl groups. _______________________________ edit: nevermind i found it, its prop-2-yl apparently. wow this forum has like no people at any time.

To make 2,4,6-trimethylbenzyl chloride, I have to use 1,3,5-trimethylbenzene and react it with formaldehyde and HCl. Ive gotten started but now im stuck. So the H-Cl protonates the formaldehyde making that carbon delta positive. this carbon can now be attacked by one of the carbons of the 1,3,5-trimethylbenzene at any of the available spots. creating an OH where the Cl needs to be. How do i get rid of the OH now in order for the Cl to attack? I was thinking of protonating the OH with another molecule of HCl and then allowing an SN2 reaction to take place so the Cl can attack and replace the OH. But i have a feeling that I've done something wrong?

nevermind stupid idea if admin can delete this thread like my last one, please do thanks

Hello: How does an atom determine whether it will form a covalent bond or an ionic bond? Does electronegativity have anything to do with it? Thanks for your help in advance!

The FDA has opted to regulate tobacco, and as such, the tobacco companies will be required to list alot more of the ingredients within cigarettes. Id like to ask all of the biochemists or chemists out there if the tobacco plant contained any more of those crazy sounding chemicals (like hydrooxytetra-ect ect) than any other organic plant that went through the same curing process and was smoked. Or do almost all plant contain them, its just that not all plants are inhaled like tobacco is? Thanks for the help

Why is BORAZOLE B3N3H6 "inorganic Benzene" more reactive than Benzene ????? Pls guys help me out !

gd day to all out there. basically the land i am in, no heavy duty or even medium firepower chem is allow. imagine going to get permit with local auth for get hcl at 37% con. best con is at 8.3 from a cleaner. my logic to get high con for hcl is to bubba more hcl in. no high con for sulfuric acid...so making 1...damn reducing water by heating i do not know my current con for battery water...able to guess? white fume signal when reflux= ??? what con i do a bath...started water and it seem long... replace oil. acceptable. got a reflux adaptor with no condenser and some glass ball bearing from martell bottles during clubbing sessions in the …

Hello, I am a biological/process engineer. I am trying to scale down the anthrone/carbohydrate assay to reaction volumes in the 25-50 uL range. I have a few questions. Does the latent time between when one adds anthrone reagent (anthrone + 70-75% H2SO4) to the carb. source or unknown until the reactions are brought to boiling effect the assay? How long is the color of the completed assay stable? Does anthrone bind to cellular material thereby skewing the results? Can an anthrone concentration lower than 175 mg/mL be used in this reaction? Has anyone successfully scaled this assay down to be conducted in microplates? Thanks, Peter

Hi everyone, I have a pretty simple question on nucleophilicity in a polar protic solvent. Is it true that usually the more stable the charge is, the better the nucleophile is in a protic solvent? If so, why is carboxylate ion a worse nucleophile than ethoxide ion? I thought the resonance stabilized the carboxylate ion to decrease its electron density, thus the protic solvent has less of an effect in shielding it from the electrophile. Thanks in advance

Hi everyone I have two questions. 1. How can I predict the stereochemistry of the reaction of (S)2-methoxy-®4-methoxy-3-hexanone with tetramethyl ammonium triacetoxy borohydride. What face will it attack from? 2. The reaction of 3(S)-hydroxy-4(S)-isopropylcyclohexanone with sodium triacetoxy borohydride. What will be the stereocenter of the aclohol? What face will it attack from in this case? I heard my TA joined this forum and I would like to get an answer from her or someone in her group that took the class from the same prof before. He is on my comps committee and I need an answer to these questions to finish my molecule. Cheers

I am thinking of synthesising the polymer poly-(L-Lysine) and copolymer poly-(L-lactic-co-epsilon-caprolactone) for use in electrospinning of an ECM scaffold; just for fun! I was wondering if there was anything that comes to mind immediately why I shouldn't try to do this? I personnaly can't see anything wrong with any steps of these synthesis. Merged post follows: Consecutive posts mergedNo strings of capitals in titles eh?

Hey, I'm having a little trouble figuring out all the forms in which methyl orange can bind to wool. So if anyone could help me out with this that would be great Thanks.

Hi to all. I am a synthetic chemist with a difficult problem. I wanted to oxidize 3-hydroxyglutaronitrile to a ketone. I already tried using the standard Cr2O3/ sulfuric acid method. However, after 9 days at 85 oC I only got some crap and some starting material. I understand that the electron withdrawing groups (2 nitrile groups) are making this oxidation difficult. Anyone? Help please. (I am now investigating this oxidation because SN2 reaction of 1,3-dibromoacetone to 3-ketoglutaronitrile using KCN is very problematic. I tried using diferent solvents such as DMSO, DMF etc. but still no reaction.)

hi evrey one, i saw a candle that burn with blue flame, i know that metals give the blue flame but the qestion is how can a a fuel that solve metals? maybe ethanol wax was some one who told me but i cheeked that ethanol gel have Ca2+ that will ruine the color of the flame. any sugestion what can fuel low in carbon wax like strukture solve metals för those candels that burn with color flame? thanx för answering:-)

Okay first post and i am totally confused. Looking at the cation exchange, how does the plant root which is negatively charged, get the cations which are positively charged (Ca, Fe, K ect...), that have bonded not to the plant root, but has bonded to the negatively charge clay and organic matter particles? Thanks
