Question

In Friedel-Crafts alkylation of aniline, one gets ______.

Options

• alkylated product with ortho and para substitution 

• secondary amine after acidic treatment

• an amide product

• positively charged nitrogen at benzene ring

Answer 1

In Friedel-Crafts alkylation of aniline, one gets positively charged nitrogen at benzene ring.

Explanation:

Since, anniline does not undergo Friedel-Crafts alkylation because of salt formation with AlCl₃. So, because of this nitrogen acquires positive charge.
