Acetone reacts with hydrogen cyanide (HCN) to form a cyanohydrin. It is an example of?

Correct answer: D. Nucleophilic addition

  • A. Electrophilic addition
  • B. Electrophilic substitution
  • C. Nucleophilic substitution
  • D. Nucleophilic addition

Explanation

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.

About Aldehydes and Ketones

Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
