Assign a reason for the following statements: Alkylamines are stronger bases than arylamines. (b) How would you convert methylamine into ethylamine? |
|
Answer» Solution :(a) Itis because in ARYLAMINES the `NH_(2)` group is attached directly to benzene ring. It results in the unshared electron pair on nitrogen atom to be in conjugation with the benzen ring and tyhus making it less available for protonation whereas alkyl group are electron releasing group. (b) `underset("Methylamine")(CH_(3)NH_(2))+HNO_(2) to cH_(3)OH OVERSET(PCl_(5))(to) CH_(3)CL overset(KCN)(to) CH_(3)C-=N underset (4[H])overset(Na//C_(2)H_(5)OH)(to) underset("Ethylamine")(CH_(3)CH_(2)NH_(2))` |
