a)electrophilic addition
b)electrophilic substitution
c)nucleophilic addition
d)nucleophilic substitution ​

Answer 1

Answer:nucleophilic addition reaction

Explanation:

Answer 2

Acetone reacts with HCN to form a cyanohydrin. It is an example of nucleophilic addition.

• Acetone reacts with HCN to form a cyanohydrin. It is an example of a nucleophilic addition reaction of a carbonyl compound.
• In this reaction, the cyanide ion attacks the carbonyl group of acetone and acts as a nucleophile. In the next step by protonation, the cyanohydrin is produced.
• Hence the correct option is c.
