Hydrocarbons

Compound X on reaction with $O_{3}$ followed by $Zn/ H_{2} O$ gives formaldehyde and 2-methylpropanal as products. The compound X is:

A.Pent-2-ene
B.3-Methylbut-1-ene✓
C.2-Methylbut-1-ene
D.2-Methylbut-2-ene

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
