Give simple chemical tests to distinguish between the following pairs of compounds.
Acetophenone and Benzophenone

Explanation

Acetophenone `(CH_(3)COC_(6)H_(5))` and Benzophenone `(C_(6)H_(5)COC_(6)H_(5))` : Acetophenone contins `CH_(3)CO` group, as such it will give iodoform test wit `NaOI(NaOH + I_(2))` while no such group is there in benzophenone, as such it will not give iodoform test.
`underset("Acetophenone")(CH_(3)COC_(6)H_(5)) + 3NaOI rarr C_(6)H_(5)COONa + underset("Iodoform (Yellow ppt.)")(CHI_(3)) + 2NaOH`
`underset("Benzophenone")(C_(6)H_(5)COC_(6)H_(5)) + NaOI rarr` No yellow ppt. of `CHI_(3)`.
