The major product is p-bromo N,N,N -trimethylaniliniumiodide when p-bromoaniline react with excess CH₃I.
When p-bromoaniline react with methyl iodide it produces p-bromo N,N-dimethylaniline.
When p-bromo N,N-dimethylaniline reacts with excess methyl iodide leading to the production of p-bromo N,N,N -trimethylaniliniumiodide.
Thus from the above conclusion we can say that The major product is p-bromo N,N,N -trimethylaniliniumiodide. when p-bromoaniline react with excess CH₃I.
