Ethyl Acrylate conformational analysis

Post by classicfan »

Hello, everyone!

I am analyzing the molecule ethyl acrylate Image right now and having a little trouble because I've, unfourtunately, fallen behind in my organic chemistry course at the moment.

What is the most stable conformation of ethyl acrylate?

Thank you very much in advance Smiley

There are sp3 and sp2 carbon atoms in the molecule, but no chiral atoms. Chiral carbon atoms usually have all four different substituents, so their mirror image can't overlap with the original.
Unlike flexible single C-C bond, carbon-carbon double bond C=C has restricted rotation. This make possible cis-trans isomers for such molecules except in this particular case H2C= is the same even if both hydrogens switch their positions. Cis-trans isomers would be possible for molecule MeCH=CHCOOMe, but not in your molecule.
Remember safety first! Check MSDS and consult with professionals before performing risky experiments.
