Cis and trans stereoisomers
Web(a) The cis and trans stereoisomers of 2-butene are achiral. (b) The carbonyl carbon of an aldehyde, ketone, carboxylic acid, or ester cannot be a stereocenter. (c) Stereoisomers … WebJul 25, 2024 · Cis- isomers tend to have higher boiling points than their trans- counterparts. Trans- isomers generally have lower melting points and have lower densities than their cis- counterparts. Cis- isomers collect the charge on one side of the molecule, giving the molecule an overall polar effect.
