Oxygen is far more electronegative than carbon and so has a strong ... up a
carbon-oxygen double bond is even more easily pulled towards the oxygen.

Hence in ethalnal -OH group is present and the nucleophile easily attaches on oxygen than -CHO in propanone.

but there''s no -OH group in ethanal , a -CHO group is there....

Better electrophile has greater reactivity towards nucleophilic addition reaction. As ethanal is better electrophile than propanone

it is more reactive towards nucleophilic addition reaction.

Propanone is a weak electrophile than ethanal because it has two methyl groups which contribute to +I effect
