1,2-diols are oxidised to ketones or aldehydes by periodic acid `HIO_(4)`. Periodic acid reacts with dipol to form a cyclic intermeditate. The reaction takes places because iodine is in a highly positive oxidation state, so it readily accepts electrons. When the intermeidate breaks down, the bond between the two carbon bonded to the OH group break.
