1.	Out of acetophenone and benzophenone, which gives iodoform test? Write the reaction involved.
Answer» The compound should have CH₃ CO-group to show the iodoform test. Acetophenone (C₆H₅ COCH₃) contains the group CH₃CO attached to carbon and hence given iodoform test while benzophenone does not contain this group and hence does not give iodoform test. C₆H₅ COCH₃ (Acetophenone) + 3I₂ + 4 NaOH → CHI₃ + C₆ H₅ COONa (Iodoform) + 3 NaI + 3 H₂O C₆ H₅ COC₆H₅ + I₂ + NaOH → No reaction Acetophenone will respond to iodoform test when treeated with I2/NaOH(aq) as it contains keto-methylje group Reaction CH3COC6H5+I2+NaOH-> CHI3+C6H5COONa+NaI+H2O

Answer»

The compound should have CH₃ CO-group to show the iodoform test. Acetophenone (C₆H₅ COCH₃) contains the group CH₃CO attached to carbon and hence given iodoform test while benzophenone does not contain this group and hence does not give iodoform test.

C₆H₅ COCH₃ (Acetophenone) + 3I₂ + 4 NaOH → CHI₃ + C₆ H₅ COONa (Iodoform) + 3 NaI + 3 H₂O

C₆ H₅ COC₆H₅ + I₂ + NaOH → No reaction

Acetophenone will respond to iodoform test when treeated with I2/NaOH(aq) as it contains keto-methylje group

Reaction

CH3COC6H5+I2+NaOH-> CHI3+C6H5COONa+NaI+H2O
