Step-by-Step Solution
VerifiedAnswers
The products formed in the given reactions are shown below.
Halogenation is carried out by treating a carbonyl compound that has alpha hydrogens with a halogen in the presence of a base. When excess halogens are present, all the possible acidic protons get replaced with halides.
The first step involves the abstraction of the proton by the base. The second step is the formation of an enolate. The third step involves the attack of enolate on electrophile in the presence of the base.
