Q. A compound (X) on ozonolysis followed by reduction gives an aldehyde $C_{2}H_{4}O$ and 2-butanone, compound (X) is

A) 3-methyl pentene-2
B) 3-methyl pentene-3
C) 3-methyl hexene-3
D) 3-ethyl pentene-3
Explanation

(a)
O
$\parallel \$
$X\underset{(ii)Zn/AcOH}{\overset{{\ \ \ \ \ \ \ \ (i)O}_{3}\ \ \ \ \ \ \ \ \ \ \ \ }{\rightarrow}}C_{2}H_{4}O + CH_{3}CH_{2} - C - CH_{3}$
Aldehyde 2-butanone
The aldehyde should be $CH_{3}CHO$ because the molecular formula is $C_{2}H_{4}O$.
