WebDec 1, 2015 · 3.3.8 Aldehydes and ketones (A-level only) Aldehydes, ketones, carboxylic acids and their derivatives all contain the carbonyl group which is attacked by nucleophiles. This section includes the addition reactions of aldehydes and ketones.
WebThe carbonyl compounds usually undergo nucleophilic addition reactions due to the polarity of the C = O bond. The carbonyl group is having a co-planar structure & its carbon atom has sp2 hybridization . The C=O bond breaks due to the nucleophilic attack and results in the breakage of the pi-bond. ihealthy infirmary health portalWebThe newly formed carbonyl group is an aldehyde and it is more reactive than the ester, thus is attacked one more time by LiAlH 4: This, again, is very similar to what we saw in the Grignard reaction of esters.
