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.

Text Solution

Verified by Experts

`DU` in `(D) =((2n_(C )+2))/2=((2xx8+2)-10)/2=4^(@) (C:H~~1:1)`
So, it must contain benzene ring, and `(MeCO-)` group, since it gives iodoform test. The structure of compound `(D)` may be `(Ph-CO-Me)`.
