Ketones are symmetrical or mixed depending on the two attached alkyl groups; acetone gives a positive iodoform test with sodium hypoiodite.

Classification of aliphatic ketones by structure:

  1. Simple (symmetrical) ketones: Both alkyl/aryl groups attached to the carbonyl carbon are identical, e.g. CH3−CO−CH3CH_3-CO-CH_3 (acetone, dimethyl ketone).
  2. Mixed (unsymmetrical) ketones: The two groups attached to the carbonyl carbon are different, e.g. CH3−CO−C2H5CH_3-CO-C_2H_5 (methyl ethyl ketone, butan-2-one). Action of sodium hypoiodite on acetone (iodoform reaction): Acetone, having a methyl ketone group (CH3CO−CH_3CO-), reacts with sodium hypoiodite (generated from I2I_2 + NaOH) to give a yellow precipitate of iodoform: …
