Vedclass · Answer

(C) The correct matching is as follows:$P$ (Acetylene) undergoes cyclization to benzene,followed by nitration,reduction,diazotization,and hydrolysis to yield $C_6H_5NO_3$ (Scheme $III$).$Q$ (Resorcinol) undergoes sulfonation,nitration,and desulfonation to yield $C_6H_5NO_4$ (Scheme $IV$).$R$ (Nitrobenzene) undergoes reduction,acetylation,sulfonation,nitration,desulfonation,and hydrolysis to yield $C_6H_6N_2O_2$ (Scheme $II$).$S$ ($p$-Nitrotoluene) undergoes oxidation of the methyl group to carboxylic acid,followed by conversion to acid chloride and then amide to yield $C_7H_6N_2O_3$ (Scheme $I$).Thus,the correct sequence is $P$ $\rightarrow 3, Q$ $\rightarrow 4, R$ $\rightarrow 2, S$ $\rightarrow 1$. Hence,the correct option is $(C)$.

Match the four starting materials $(P, Q, R, S)$ given in List-$I$ with the corresponding reaction schemes $(I, II, III, IV)$ provided in List-$II$ and select the correct answer using the code given below the lists. Codes: $P \quad Q \quad R \quad S$
