Question
There are two paths to prepare a compound (A) (2-methyl-hex-1-en-3-yne). Which of the following statements is correct?
- Path I is feasible
- Path II is feasible
- Both paths are feasible
- Both paths are not feasible
The correct answer is: Path II is feasible
In path I, 
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
