An unsaturated hydrocarbon \([\mathrm{A}]\) undergoes the following series of reactions. Identify \([\mathrm{A}]\).
- A But-1-yne
- B But-2-yne
- C But-2-ene
- D Propyne.
Answer & Solution
Correct Answer
(B) But-2-yne
Step-by-step Solution
Detailed explanation
The hydrocarbon [A] reacts with ammoniacal \(AgNO_3\) to give no reaction, which indicates that it is not a terminal alkyne. This eliminates but-1-yne and propyne. The reaction of [A] with \(Na/liquid NH_3\) gives a trans product, which is a characteristic reaction of internal…
