I recently heard that during some period of time Purina pet food was being produced from crude oil via a set of complex chemical transformations. Which, I think, is mostly bluff and marketing. So is it possible, and have somebody had any real positive practical experience of getting amino acids f...

Are these reaction mechanisms correct for Ammonia and Bromide anions acting as a base respectively?

I watched a Khan academy video on organic chemistry functional groups. It mentioned the amine and amide groups. From what I see, an amide is an amine with a carbonyl group. However, the internet says that that assumption is wrong. I am guessing it has to do with the "R" groups on the amine funct...

I was wondering, when working in a lab in an area related to organic compounds, when and why would a chemist consider the enantiomeric excess % and how would a chemist used that information?? Same Thing goes with specific rotation, why, how, and when would a chemist use this? I was just curious b...

This question is about resveratrol in wine or grapes and not in some special delivery system. If one is drinking some wine or eating grapes, does it matter if they keep it in their mouth a bit so the resveratrol within the wine or grapes get absorbed better? I know now all nutrients can be gott...

Hi im searching for atmospheric data on the following: Air quality, Dust Particle Concentration, Pollution, Average Temperature etc for various cities such as Frankfurt, London, Hong Kong, Bangkok... Are there any websites that can give me this data (or similar atmospheric measurements) for e...

From an article in the New Scientist in 2010, Since pre-industrial times, methane levels in the atmosphere have risen from around 715 parts per billion to nearly 1800 ppb, claims Folberth. "If methane could be taken back to pre-industrial levels it would bring about half a degree of cooling ...

It's been over a semester since my most recent chemistry class, (general chemistry 2) because I could not take organic at my community college. It is only considered a sophomore level class unless taken in-residence at the university I am transferring to (understandable). I was curious if I could...

I know the Cannizzaro reaction takes place in carboxyl compounds without $\alpha$-H with the regular examples being formaldehyde and benzaldehyde. But can this reaction take place with say diphenylmethanone or di ter-butyl ketone(2,2,4,4-tetramethylpentan-3-one) or 2,2-dimethylpropanal ? I coul...

Original Question Posted 8/31/15 We are trying to predict what will happen when Carbon Dioxide gas is introduced into a contact chamber that serves as an Ozone Contact Chamber. These Contact chambers presently oxidize compounds found in Municipal Pool Water along with Chlorine at below 5ppm. the...

should chemical formula of ethanol be written as $\ce{CH3CH2OH}$ or $\ce{C2H5OH}$ ? And whats the logic behind it? I have seen the former being used more often, so why is ethane represented by $\ce{C2H6}$ than $\ce{CH3CH3}$?

I'm in class right now and my teacher put this up on the board as a representation of 1,2-dichloroethane. He also projected a model. I'm thinking ... his board drawing is wrong. Shouldn't the chlorines also be on dashes too? There's no way the chlorines can be in the same plane as the carbon atom...

If I have list of various chemical compositions, lets say 1) Composition contains A ( 5-10 wt. %), B (5-70 wt. %) and C (rest) 2) Composition contains A (10-20 parts by weight), B (0.5-3 parts by weight) and C (rest) 3) Composition contains A (5-10 weight parts), B (30-40 weight parts) and C (re...

I have a problem with this graphic, specifically the right hand side. Why a "sextet" atom (an atom with 6 valence electrons)? I thought only a select few elements (C, N, and O) actually follow the octet rule.

I could not find this anywhere on the net. I am asking what is amine inversion and how does it affect basicity? For instance why is $\ce{Et3N}$ less basic than cyclohexyl-amine despite the $+I$ from ethyl groups.

I just had my biology test paper back from my teacher, and my teacher insisted that when functioning as a buffer in an alkaline solution, the amino acid deprotonates by the ammonium group instead of the carboxyl group, because amino acids in solution are mostly zwitterionic. I thought zwitterions...

I am working on a project using methylene blue as photo-initiator for a polymerization reaction. In this classic reaction methylene blue will get reduced into leuco-methylene blue in presence of some amines as sacrificial donor. As I looked into the literature, almost all reactions involving MB-...
