Vedclass · Answer

(C) The correct answer is $C$.$A$. $R-NH_2 + 3 R-X \rightarrow R-N^+(R)_3 X^-$ is known as Hofmann exhaustive alkylation.$B$. $R-CONH_2 + Br_2 + 4 KOH \rightarrow R-NH_2 + K_2CO_3 + 2 KBr + 2 H_2O$ is known as Hofmann bromamide degradation.$C$. The reduction of amides $(R-CONH_2)$ to amines $(R-CH_2-NH_2)$ using $LiAlH_4$ is a standard reduction of amides,not Mendius reduction. Mendius reduction specifically refers to the reduction of nitriles $(R-CN)$ to primary amines $(R-CH_2-NH_2)$ using $Na/EtOH$ or $H_2/Ni$.$D$. The reaction of quaternary ammonium salts with moist $Ag_2O$ followed by heating is known as Hofmann elimination.
