Acetophenone and Benzophenone can be distinguished using the iodoform test.

Iodoform test:

Methyl ketones are oxidized by sodium hypoiodite to give yellow ppt. of iodoform. Acetophenone being a methyl ketone responds to this test, but benzophenone does not.
C6H5COCH3 + 3NaOI → C6H5COONa + CHI3 + 2 NaOH
C6H5COC6H5 + NaOI → No yellow ppt of CHI3
