Dear Student,
 
(a) Carboxylic carbon is less electrophilic than the carbonyl carbon as the presence of two electronegative oxygen atoms.
 
(b) The presence of a partially positive α carbon in propanal compared to the fully substituted α carbon in propanone makes it more reactive towards addition of HCN.
