Question

(A) $(1)$ Aniline is a Lewis base and reacts with the Lewis acid $AlCl_3$ to form an anilinium ion complex,which strongly deactivates the benzene ring

Vedclass · Accepted Answer

$C_6H_5NH_2 + AlCl_3 + CH_3Cl \rightarrow p-CH_3-C_6H_4-NH_2$

Vedclass · Answer

(A) $(1)$ Aniline is a Lewis base and reacts with the Lewis acid $AlCl_3$ to form an anilinium ion complex,which strongly deactivates the benzene ring. Therefore,Friedel-Crafts alkylation does not occur.$(2)$ Sulfonation of aniline with $H_2SO_4$ produces anilinium hydrogen sulfate,which upon heating at $473-513 \ K$ gives sulfanilic acid $(p-aminobenzenesulfonic acid)$. The reaction shown in option $B$ is a standard representation of this process.$(3)$ Acetylation of aniline with acetic anhydride in the presence of pyridine is a standard reaction.$(4)$ Nitration of aniline in acidic medium gives a mixture of ortho,meta,and para-nitroaniline due to the protonation of the amino group,but the para-product is a major component.
