The compound should have CH3CO group to show iodoform test . Acetophenone (C6H5COCH3) contains the group CH3CO attached to carbon and hence give iodoform test . Which benzophenone does not give iodoform test .
 
C6H5COCH3 + 3I2 + 4NaOH give CHI3 + C6H5COONa + 3NaI + 3 H2O
 
C6H5COC6H5 + I2 + NaOH give no reaction
 
C6H5COC
