Organic Chemistry

:confused: Hi guys I dunno if yall remember me but I took a good long break from SFN but I'm back cuz I love science (lol) Anyway I also need your help. Um it would be helpful if someone explains how chiral center is a type of stereocenter. I know a stereocenter is an atom that when you interchange two groups it produces a stereoisomer but how does a chiral center fit that description?? My text does a bad job of explaining

what are the products of oxidation when an organic compound undergoes oxidation process?

I am looking forward for the most plausible mechanism of the reaction between acid amide (derivative of carboxylic acid) and HNO2. although i know the general reaction ar written in my book ie. R-CONH2 + HNO2 == (HEAT) == >R-COOH + N2(evolved)+H2O mechanism would hel me identifying which kinds of acid amides and participate in such reactions.

There's a question i did which got me thinking (I have tried searching a reason for it but to no avail) so is it possible for CH3CH2CN(l) + NaOH(aq) to produce ammonia gas when heated? As far as I know, it's amide which produces ammonia gas when it is refluxed with NaOH(aq). So does that mean somehow or other, CH3CH2CN(l) is turned into amide? If so, how? and... if not? how is it possible that the nitrile compound releases NH3(g)? If it's possible, please insert the chemical equations/mechanisms too. Thanks

Hi all, I'm very unexperienced in GC and I'm currently analyzing some crude oil samples but seem to have a problem or maybe not, I dont know. I added 5% Tetralin (C10H12 or 1,2,3,4-Tetrahydronaphthalene) to some of the crude oil samples, and anticapated expected the C10 group to increase noticeably but what I observed was that the C12 group increased. And this is in six different samples, whats happening here. thanks

This is crazy. Can someone explain the science behind this? http://www.metacafe.com/watch/734784/gel_o_shot_inside_a_banana/ This guy is supposedly making a Jello shot inside a SEALED banana. Scientifically speaking, how is that possible?

Why we get tears when we cut onions? Which chmeical brings tears? What is tear gas? Generally people use onion to reduce irritaion when exposed to tear gas? How does onion help? Thabks

why are s0me alc0h0ls s0luble in water?

What is the mechanism of the Diels-alder reaction of furan and maleic anhydride? Also, tetrahydrofuran was also added, if that helps? THANKS!

Hi, Can somebody out there provide some molecules which can be synthesised. Thanks

Hello everybody, I cannot find the reaction mechanism for this synthesis. It is for a report (:$), and they want to see a reaction mechanism and reaction equations. It doesn't have to be stochiometric correct i.m.o., but the basic route should be correct. I am a university chemist student, but I don't know how to solve this one... Can someone help me solve this one? ciao!

What are geometric isomers? iv'e been having trouble understanding what they are and what they are for. thanks in advance!

Does anyone know the full reaction mechanism for this reaction? Apparently the order of reaction with respect to HCl is 0 bu i got it different in experiment. If i understand the full reaction mechanism it may help me to interpret my results. This is for A level Chem coursework Thanks.

hi would anyone please help me? what is allyl cation? thanks a lot

I'm interested in plants and a number of them contain 'cyanogenic glucosinolates' that break down to form cyanides. Some of them even contain hydrogen cyanide in a raw state. I was curious to know if there was a way to process the plant material to remove the cyanide content. One is to bake the mushed up plants, but that doesn't do a lot for the actual plant material you want left. Is there a chemical method for moping up and making safe the cyanide radicals?

does anyone have any knowledge about the synthesis of any of the following dyes, or any other fluorescent dyes for that matter that I could possibly make without too much effort and resources, provided of course, i dont get any poisonous gases ; 9,10-diphenylanthracene 9,10-bis(phenylethynyl)anthracene 5,6,11,12-tetraphenylnaphthacene I was previously extracting dyes from the lightsticks but they're damn expensive! (around $1.20 per 20mL the cheapest i got)

Hi everyone. I was wondering if anybody could help me with this syntheses. I can't figure out how it works. Sorry if the drawing is a little messy.

Hi everyone. My first post here. I had trouble figuring this problem out. Any help would be greatly appreciated. The problem asks to use Robinson annulation reaction to synthesize this compound. The books gives a hint about having an intermediate Michael addition product. Thanks in advance.

How do the conditions for nitration of methyl benzoate differ from those for the nitration of benzene? what is the mechanism nitration of methyl benzoate to form methyl 3-nitrobenzoate? Thanks.

I have 2-trimethylsilylthiophene and need to make it 3-trimethylsilylthiophene. I know solvents can have an effect on how and where molecules are placed, etc. but not sure how to do it in this case. There will be mercury involved somewhere I think, or perhaps mercury replaced by iodine..? Basically I'm confused and wonder if anyone has any insight on where to even begin, or just a book/website that is good for explaining how to go about this stuff..? Cheers

Can any one of U tell me the preference order of functional groups while naming to compound having more than one functional groups (by IUPAC system)

Ok, am at a reealy basic level of chemistry...I need to react C6H5C=OOH with SOCl2. I don't know where to begin as I'm not sure what would go where, and if anything would be bumped off and what would be left over. I don't just want the answer to this question as I need to do quite a few like it, but I need to know how it's done, what the rules are, etc. I would look it up but I don't know what it's called! Can I please get some advice on where to begin/where online is a good tutorial site/what this 'reaction method' is called? Ta very much:)

Hi All, My first post. Basically I'm from computer background and is very new to orgranic chemistry. You must be wondering why I'm here. Well, I develop softwares for my client who are basically from chemistry background. They want me to develop a chemistry related application where the user should be able to create molecules, set varius properties, see 3D view of molecules and view the synthesis result. The application that I'm developing is quite similar to "Chemsketch" but my application has options to see the synthesised results. This means you have a goal molecule. Now to achieve that goal molecule you may have various steps to obtain. My application determi…

I'm trying to write out the reaction mechanism for the formation of acid rain from atmospheric nitrogen. I know the general equations to go through but when it comes to showing the movement of electrons with 'curly arrows' I get stuck! so far this is what i have: 1. O + N≡N → N=O + N 2. N + O=O → O + N=O 3. 2N=O + O=O → 2O=N=O 4. N=O + O=O=O → O=O + O=N=O 5. O=N=O + O-H → H=O=N=O ¦¦ O I know that electrons from the triple bond of the nitrogen in step 1 move to one N atom and this means that the O is attracted to the other N and they form NO. I can also complete number 2 (i thin…

Hi, I heard about this that in electrophlic addition in alkenes, bromine attaches to the end of alkene molecule that have less number of carbon atoms. They were calling it a marconi carb rule sort of thing. If any one knows about it or something similar could you tell me and explain it to me what it is? I would appreciate it!
