These are distinguish by the iodoform test. The main criteria is the presence of free ethyl group.
Since acetophenone contain a free methyl group therefore it will give a positive iodoform test.
C6H5COCH3 + 3NaOI --→ C6H5COONa +
Acetophenone Sodium Sodium benzoate.
Hypiodite
CHI3 + 2 NAOH
Iodoform

Benzophenone does not contain any free methyl group therefore, it will give a negative iodoform test.
C6H5COCH3 + NAOI --→ No yellow part (CHI3) Benzophenone
