Hi there, I was wondering if there is a quick and easy way to assign an R or S configuration to a chiral enantiomer instead of either setting the lowest priority molecule back into the plane, or having to physically build the model using a modelling kit. Also, is there any quick way to identify a meso compound? Thanks. PS Am I correct in saying that the top left compound is an R-entantiomer whereas it's mirror image is an S-enantiomer?

trying to basify and oil that is pH 7. Dumped straight into a 35% NaOH sol., mixed very well, extracted with DCM, distilled off DCM, but result was a paltry pH 7.8. Am I missing something here? If I dissolve in solvent such as MeOH or IPA first will this help in the basifying process? thanks!

Hi I am new to this forum, so this will be my first post. I am curious to know if there is any way to reverse the oxidation reaction of ethyl alcohol in to acetic acid.

In our instrumentation lab we have been using a polarimeter on salicylic acid tp measure the degree it rotates plane polarised light, I understand that it does this and the applications of this but Im confused about HOW it does this, I know it has something to do the vibration of molecules. If someone could help me clear this up I would appreciate It.

I am a young farmer searching for a recipe for liquid fertilizer. I would like to find a simple mostly organic formula. If any body has any advise I would be extremely gratefull.

I've recently frozen some guacamole with listeria in it. The original pH was about 6.5 then we added some citric and ascorbic acid, bringing the pH down to about 4.9 - tested several times. When removed and thawed out the listeria died off more than expected so we tested the pH again to find that it had gone below the critical level of 4.1. What might make it drop by this much? I know pH is affected by temperature, but could it have a lasting effect even once thawed and back at room temperature? Obviously everything was not back in its pre-frozen state so I'm thinking it was permanently damaged and that's perhaps why the pH was different. But do -10 and -20 degrees take …

Thymoquinone is not soluble in water. What solvent can be used to make a concentrated solution from 99% thymoquinone powder.

If you have an old amo bunker full of amo dating back to WW11 and the bunker is to unsafe to enter due to tnt that leached from the shels and crystalised on the outside. What can you do to make it safe.

Somebody help me with this equation ethanol+iodine C2H5OH+3I2→....... above the arrow is (NaoH) , but of course I can't write it here. Please somebody help me work this out

.Something that isn't consumed by the reaction (so say A) is dissolved at the same time as something that is consumed by the reaction (B) in a solvent, so that they are in the same phase...what is this reaction an example of? Part2) What is the most pervasive particle that is involved in an example of this type of reaction that isn't consumed by the reaction?

I'm sorry if this should go in the inorganic forum, but petroleum ether sounds like an organic compound to me. Anyway, this may sound like an odd question, but can one get petroleum ether from a local commercial outlet, or is there a lot of restriction to obtaining it? I live in Canada, BTW.

Hi, I have a problem figuring out the Mechanismus for this rxn: 2-nitroresorcinol + 4-penten-1-ol --> 2-Nitro-1,3-bis(pent-4-enyloxy)benzene --> 2,6-Bis(pent-4-enyloxy)aniline Hope someone can help me with this, sumi

The first azo dye was made by reacting aniline (phenylamine) with potassium dichromate. Anyone knows the mechanism or the products? Thank you very much!

How to calculate the ratio of monomers (one monomer in excess) in polycondensation to get desired molecular weight? Is it possible?

The Nobel Prize for chemistry in 2010 went to Richard Heck, Ei-ichi Negishi and Akira Suzuki for their work with organopalladium catalyzed cross couplings. Examples include: Suzuki Reaction: Heck Reaction: where the palladium catalyst is often an organopalladium(0) species such as tetrakis(triphenylphosphino)palladium(0). I have a feeling this chemistry will change future organic classes significantly. Now there is finally a way, though not entirely unrestricted, to just piece together linear alkyl and alkenyl fragments like toy bricks. There have been reactions like this reported before, see the dreaded "Wurtz-type couplings" but t…

DHMO also known as hydric acid is a major component of acid rain and can cause severe burns. This same substance usually has a very high concentration in soft drinks and is readily available to many households. So you think there should be government controls restricting access to this chemical? Discuss. N.B: Should be under Inorganic Chemistry, sorry about that.

what happens to the molecular stucture of diamond at the surface? because there is obviously no other carbon atom to bond to.

The title states it all: a) Would the 2 chemicals react B) If so, what would the products be? A few things i could guess: 1) CH3-CH3 + H2O2 -> 2 H2O + CH2=CH2 2) CH3-CH3 + 2 H2O2 -> 2 H2O + HO-CH2-CH2-OH 3) CH3-CH3 + H2O2 -> H2O + CH3-CH2-OH Thanks in advance!

Can anyone point me to, or diagram out, an electron pushing diag for the dehydration of formic acid by sulfuric acid to form carbon monoxide. I'm especially interested in how the the CO forms with a lone pair without picking up the free H+ to form either COH of formaldahyde (CH2O). I'm also curious abot how the dative bond forms, without picking up a free H+. Thanks!

Hi guys! In class, we did an extraction lab and for the post report, I had 2 questions I had trouble with . 1. Prove he conclusion that two extractions of A with 50 mL portions of ether yield 57.8 mg of A, whereas one extraction with 100 mL of ether yields only 53.6 mg of A. 2. Calculate the volume of ether needed to remove 90% of the suberic acid from 100 mL of a saturated aqueous solution in a single extraction. Any help would be nice

is the formation of diamond from graphite (under extreme heat and pressure) exothermic, endothermic or neither? also, while we're at it, is there a way of telling whether a reaction will be exothermic or endothermic? hang on, i think this is in the wrong place, how do you move it?

1)Why can the use of high temperatures in the catalytic hydrogenation of alkenes to alkanes be self-defeating ? 2)We know that if the substituent is present at the equatorial position in cyclohexane then that compound is more stable, then why all trans-1,2,3,4,5,6-Hexaisopropylcyclohexane is a stable molecule in which all isopropyl groups are axial ?

Song based on my crush on a girl in organic class. Just a little fun if you're getting bogged down with organic. Won't make a whole lot of sense if you haven't been through Orgo 1 and 2. Enjoy!
