A)
Solution :
a) (i) $CH_3COOH \to CH_3CH_2OH$ Reagent : $L_iAlH_4/H_3O^{+}$
(ii) $CH_3CH_2CH_2OH \to CH_3CH_2CHO$ Reagent : Pyridinium chloro chromate (PCC)
(iii)
(iv) $C_6H_5COONa \to C_6H_6$ Reagent :soda lime
(b)
(i) For nucleophilic addition reaction , the increasing order of reactivity is
Butanone < Propanone < Propanal < ethanol < Methanol
(ii) For reactivity towards HCN, the order is
Acetone < Acetaldehyde < Formaldehyde
(iii) For reactivity towards nucleophilic addition , the order is
Acetophenone < p- Tolualdehyde < Benzaldehyde < p- Nitrobenzaldehyde
