There are two paths to prepare a compound $$(A)$$ ( 2-methyl-hex-1-en-3-yne.) Which of the following statements is correct?

APath I is feasible.
BPath II is feasible
Correct Answer
CBoth paths are feasible.
DBoth paths are not feasible.

Solution

In path I, $$SN^2$$ reaction is not possible because $$RX$$ is unreactive vinyl bromide. In path I, nucleophilic addition reaction is favoured - anion is a strong nucleophile - to give the product which on hydration gives compound $$A$$.
