Benzaldehyde and acetophenone can be distinguished by the following tests.
(a) Tollen's Test
Aldehydes respond to Tollen's test. Benzaldehyde being an aldehyde reduces Tollen's reagent to give a red-brown precipitate of Cu2O, but acetophenone being a ketone does not.
(b) Iodoform test
Acetophenone being a methyl ketone undergoes oxidation by sodium hypoiodite (NaOI) to give a yellow ppt. of iodoform. But benzaldehyde does not respond to this test

hello friend!!
distinguish test between benzaldehyde and acetophenone:
a) tollen's test: benzaldehyde being an aldehydic group react with tollen's reagent to from a red-brown precipitate , since acetophenone is a ketonic group it does not react with tollen's reagent.
b) iodoform test: since acetophenone is a methylketone , it undergo oxidation by sodium hypoiodite (NaOI) to form yellow precipitate. but benzaldehyde do not react . thus distinguished.
hope my answer is useful to you.
