Question

An ester (A) with mol. formula $C_{9} H_{10} O_{2}$ was treated with an excess of $C H_{3} - M g B r$ followed by hydrolysis and the product so formed was treated with $H_{2} S O_{4}$ to give an olefin (B). Ozonolysis of (B) gave a ketone with molecular formula $C_{8} H_{8} O,$ which shows the iodoform test.
The structure of (A) is:

C_{6} H_{5} C O O C_{2} H_{5}
