Compund `X` with molecular formula `C_9H_10 O` forms a semicarbazone and gives negative Tollen's and iodoform tests. Upon reduction it gives.n - propyl benzene, Deduce the structure of `X`.

Explanation

Compund `X` with molecular formula `C_dotq H_10 O` forms a semicarbazone and gives negative Tollen.s and iodoform tests. Upon reduction it gives.n - propyl benzene, Deduce the structure of `X`.
