Q. Alkyne, $C_{7}H_{12}$, when reacted with alkaline $KMnO_{4}$ followed by acidification with $HCl$ gives a mixture of $\left( CH_{3} \right)_{2}CHCOOH + CH_{3}CH_{2}COOH$,The alkyne $C_{7}H_{12}$ is

A) 3-hexyne
B) 2-methyl-2-hexene
C) 2-methyl-3-hexene
D) 3-methyl-2-hexyne
Explanation

(c)
$\left( CH_{3} \right)_{2}CH - C \equiv C - {CH}_{2}{CH}_{3}\overset{\lbrack O\rbrack}{\rightarrow}\left( CH_{3} \right)_{2}CH_{2}COOH + CH_{3}CH_{2}COOH$
