A compund `X(C_8H_10O)` upon treatment with alkaline solution of iodine gives a yellow precipitate. The filtrate on acidifiction gives a whit solid `Y(C_7H_6O_2)` Write the strctures of X and Y.

Explanation

`underset((C_(8)H_(10)O))("Compound D")overset(I_(2) + NaOH)to underset(("yellow ppt."))(CHI_(3)darr) + compound ("filerate")underset((C_(7)H_(6)O_(2)))overset(Acid)to`compound E
Thus , this reaction indicates the presence of `-COCH_(3)` group or present of -`CHOH-CH_(3)` group in given compound D. On the basis of molecular formula of compound D and above reaction , the possible structure is given below:

Thus , this compound gives iodoform test as in following reaction (in first step this compound on oxidation with `I_(2)` gives
