Give a simple chemical test to distinguish between

Iodoform test: Methyl ketones are oxidized by sodium hypoiodite to give a yellow ppt. of iodoform. Acetophenone being a methyl ketone responds to this test, but cyclohexen-1-yl(phenyl)methanone does not.

C6H5−CO−CH3 (Acetophenone) + 3NaOI (Sodium hypoiodite) → C6H5COONa (Sodium benzoate) + CHI3 ↓ (Yellow ppt)

cyclohexen-1-yl(phenyl)methanone + 3NaOI (Sodium hypoiodite) → No yellow ppt.
