Vedclass · Answer

(C) . Benzenesulphonyl chloride $\rightarrow$ $III$. Hinsberg reagent$B$. Hoffmann bromamide reaction $\rightarrow$ $IV$. Known reaction of isocyanates$R-CONH_2 + Br_2 + 4NaOH \rightarrow R-NH_2 + 2NaBr + Na_2CO_3 + 2H_2O$Intermediate: $R-N=C=O$ (isocyanate)$C$. Carbylamine reaction $\rightarrow$ $I$. Test for primary amine$R-NH_2 + CHCl_3 + 3KOH \rightarrow RNC + 3KCl + 3H_2O$$D$. Hoffmann orientation $\rightarrow$ $II$. Anti Saytzeff (Formation of less substituted alkene as major product)Therefore,the correct matching is $A-III, B-IV, C-I, D-II$.
