There are two paths (a) and (b) for the preparation of a compound (A) (2-methylpent-1-en-3-yne), which path is correct and why? Also name the path (a) and (b).

A

Path I is feasible.

B

Path II is feasible

C

Both paths are feasible.

D

Both paths are not feasible.

Text Solution

Verified by Experts

The correct Answer is:
B
In path I, `SN^2` reaction is not possible because RX is unreactive vinyl bromide. In path II, nucleophilic addition reaction is favoured-anion is a strong nucleophile-to give the product which on dehydration gives compound A.
