Write the reactions of the final alkylation product of aniline with excess of methyl iodide in the presence of sodium carbonate solution.

Answer»

Solution :The reaction takes place in the following steps :

`overset(+)(2[C_(6)H_(5)NH_(2)CH_(3)])I^(-)+Na_(2)CO_(3) rarr underset("N-Methylaminline")(2C_(6)H_(5)NHCH_(3))+CO_(2)+2NaI`
`""C_(6)H_(5)NHCH_(3) underset(Na_(2)CO_(3))overset(CH_(3)I)(rarr)underset("N, N-Dimethylaniline")(C_(6)H_(5)N(CH_(3))_(2))`

`overset(+)(2C_(6)H_(5)N(CH_(3))_(3))I^(-)+Na_(2)CO_(3) rarr underset("N,N,N,-Trimethylanilinium CARBONATE")(overset(+)([C_(6)H_(5)N(CH_(3))_(3)])_(2)CO_(3)^(2-)+2NaI)`
