Which of the following will react with CHCl3 + alc. KOH ? (1) Thymine and proline (2) Adenine and lysine (3) Adenine and thymine (4) Adenine and proline

1. Thymine and proline
2. Adenine and lysine
3. Adenine and thymine
4. Adenine and proline

Correct answer: Adenine and lysine

Solution

Adenine and lysine are both amino compounds that can undergo reactions with chloroform in the presence of alcoholic KOH, leading to the formation of products through nucleophilic substitution. This reaction is characteristic of compounds containing amino groups, which are present in both adenine and lysine.
