An anilinium is the cation formed by protonating the amino group of aniline.
Simply a salt Anilinium acetate is formed.
I don't fcuking know. That's why I asked this fcuking question.
Since tha pka of the aniline ion is equal to 4.6, the anilinium ion is a stronger acid than the methylaminium ion, and aniline (c6h5nh2) is a weaker base than methylamine (ch3nh2).
due to we do this reaction in acidic condition here the formation of anilinium ion takesplace which is deactivating group then if we add nitration mixture substitution takes place at meta position means we don't get 4-nitroaniline
Alkyl groups are slightly electron donating. The methyl groups on the amine in N,N dimethylaniline contribute electron density to the nitrogen lone pair, making it more likely to reach out and grab a proton (ie more basic).
