Q. An ester (A) with molecular formula $C_{9}H_{10}O_{2}$ was treated with excess of $CH_{3}MgBr$ and the complex so formed was treated with $H_{2}SO_{4}$ to give an olefin (B). Ozonolysis of (B) gave a ketone with molecular formul$C_{8}H_{8}O$ which shows positive iodoform test. The structure of (A) is
A) $C_{6}H_{5}COOC_{2}H_{5}$
B) $C_{6}H_{5}COOC_{6}H_{5}$
C) $C_{6}H_{5}COOCH_{3}$
D) p-$H_{3}CO - C_{6}H_{4} - COCH_{3}$
Explanation
The correct answer is Option A: $C_{6}H_{5}COOC_{2}H_{5}$.
