Q. Compound X on reaction with $O_3$ followed by $Zn/H_2O$ gives formaldehyde and 2-methyl propanal 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
Explanation
[Solution] Joining HCHO and $(CH_3)_2CHCHO$ at the carbonyl carbons gives $CH_2=CH-CH(CH_3)_2$, i.e. 3-methylbut-1-ene. Answer (2).
