Give simple chemical tests to distinguish between the following pairs of compounds.
Acetophenone and Benzophenone
Iodoform test- Methyl ketones give positive iodoform test, so when acetophenone react with NaOI it forms Yellow ppt. of Iodoform. Whereas the benzophenone will not give ppt. of iodoform. Iodoform is CHI3 tri iodo methane. It forms only in the case when NaOI is trated with methyl ketone.
C6H5COCH3+NaOI → C6H5COONa+ CHI3+NaOH
