Correct answer is (b) 2-Methyl-3-hexyne

Q. An alkyne $C_{7} H_{12}$ on reaction with hot alkaline $K M n O_{4}$ and subsequent acidification with $H Cl$ yields a mixture of
$C H_{3} - C ∣ H_{3} C H COO H + C H_{3} C H_{2} COO H$
The alkyne is

$3$ -Hexyne

$2$ -Methyl- $3$ -hexyne

$2$ -Methyl- $2$ -hexyne

$2$ -Methyl- $2$ -hexene

Correct answer is (b) $2$ -Methyl- $3$ -hexyne
