Question: what are alpha beta unsaturated carbonyl compounds?
Answer: An enone, also called an α,β-unsaturated carbonyl, is a type of organic compound consisting of an alkene conjugated to a ketone. The simplest enone is methyl vinyl ketone (butenone, CH2=CHCOCH3). An enal is the corresponding α,β-unsaturated aldehyde, an example being acrolein (CH2=CHCHO).
