And, this compound occurs as a colourless, viscous liquid. 53 publications. Acetophenone (C6H5 COCH3) contains the group CH3 CO attached to carbon and hence given iodoform test while benzophenone does not contain this group and hence does not give iodoform test. Takeshi Takemura, Hiroaki Baba, Masahisa Fujita. Furthermore, the molar mass of acetophenone is 120.15 g/mol, while the molar mass of benzophenone is 182.22 g/mol. With a mind rooted firmly to basic principals of chemistry and passion for ever evolving field of industrial chemistry, she is keenly interested to be a true companion for those who seek knowledge in the subject of chemistry. What is Benzophenone Schott, G.W.

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