Chemistry - Carbonyl compounds Question with Solution | TestHub

An ester (A) with molecular fomula, ${\mathrm{C}}_9{\mathrm{H}}_{10}{\mathrm{O}}_2$ was treated with excess of ${\mathrm{CH}}_3\mathrm{MgBr}$ and the complex so formed was treated with ${\mathrm{H}}_2{\mathrm{SO}}_4$ to give an olefin (B). Ozonolysis of (B) gave a ketone with molecular formula ${\mathrm{C}}_8{\mathrm{H}}_8\mathrm{O}$ which shows +ve iodoform test. The structure of (A) is
