Nucleophilic addition reaction will be most favoured in :
CH3CH2CHO
CH3CHO
(CH3)2C=O
As we learnt ,
Physical properties of aldehydes and ketones -
– Due to the presence of dipole-dipole intermolecular interactions, the boiling point of aldehydes and ketones are higher than hydrocarbons and ether of comparable molecular masses.
– Solubility decreases as their molecular mass increases.
-
CH3CHO has highest charge on carbonyl carbon among all options.
