Chemical properties of Aldehydes and Ketones in of Electrons Loss of Electrons H O H3C C H + 2[H] H3C C OH H True for all secondary alcohols Carbonyl + 2[H] ─(NaBH4) Alcohol CH3CH2CHO + 2[H] CH3CH2CH2OH Propanal + NaBH4 Propan-1-ol

Chemical properties of Aldehydes and Ketones Reactions common to both Aldehydes and Ketones The difference between an Aldehyde and a Ketone is the position of the C=O (Carbonyl group). Aldehyde – always on a carbon at the end of the chain Ketone – Always on a carbon at middle carbon of the chain 1. BOTH Aldehydes and Ketones can be reduced Aldehyde reduced to Primary Alcohol Reducing agent = Sodium tetrahydroborate III (NaBH4) Ketone reduced to Secondary Alcohol ...
