Question

The haloform reaction involves the conversion of methyl ketone to carboxylate ion and haloform. Why do only methyl ketones form haloforms?

Accepted Answer

Because only methyl can have three halogen atoms on its α-carbon to form a good leaving group, only methyl ketones can form a haloform.

Answer

Because of the less steric hindrance of the methyl group, only methyl ketones can form a haloform.

Answer

Because of their higher electrophilicity, only methyl ketones can form a haloform.

Answer

None of these.
