aldol condensation of methyl ethyl ketone in Canada
Aldol Condensation Reaction ChemTalk
26/9/2022· Though aldol condensations can occur with a variety of R groups, the most common form of the reaction involves a methyl ketone and an aldehyde, which form an unbranching unsaturated carbonyl. Additionally, all aldol condensations result in a net loss of two hydrogens and one oxygen.

The aldol condensation is a classic reaction that allows two carbonyl compounds to be condensed together to give a new carbon-carbon bond, in this case a double bond. In a typical aldol reaction, a small amount of enolate is formed by deprotonation of an aldehyde or ketone. The enolate can then attack the electrophilic carbon of
