(a) Assign a reason for the following statements : Alkylamines are stronger bases than arylamines. (b) How would you convert methylamine into ethylamine ? |
|
Answer» Solution :(a) It is because alkyl groups are electron releasing (+I) -effect. Therefore, they are stronger bases than arylamines because ARYL group is electron withdrawing (-I) effect. The lone pair of electrons on N in arylamine is delocalised due to resonance with benzene ring. (B) `UNDERSET("Methylamine")(CH_(3)NH_(2))+HNO_(2) rarr underset("Methanol")(CH_(3)OH) overset(PCl_(5))(rarr) underset("Chloromethane")(CH_(3)Cl) overset(KCN)(rarr) underset("Ethane nitrile")(CH_(3)C equiv N) underset(4[H])overset(Na//C_(2)H_(5)OH)(rarr) underset("Ethylamine")(CH_(3)CH_(2)NH_(2))` |
