Solution
Rate towards Nucleophilic addition is high when electron density is low at carbonyl carbon. So, the groups attached should be electron withdrawing groups and aldehyde has high rate compared to ketone because of less steric hindrance.
–NO2 = Electron withdrawing ; –OMe = electron donating
⇒ a > b > c > d > e.
