Question

An optically active acyclic hydrocarbon (X) undergoes catalytic hydrogenation to give an optically inactive compound $C_6H_{14}$. Identify the original hydrocarbon (X).

Correct answer: A. 3-methyl-1-pentene () has a chiral center. Hydrogenation saturates the double bond to an ethyl group, yielding 3-methylpentane, which possesses a plane of symmetry and is optically inactive.
