Vedclass · Answer

(A, B, C) Let us analyze the reactions of phenol:$1$. Reaction with phthalic anhydride in the presence of $H_2SO_4$ gives phenolphthalein. Thus,$A$ is phenolphthalein.$2$. Reaction with salicylic acid in the presence of $H^+$ gives phenyl salicylate (salol). Thus,$B$ is phenyl salicylate.$3$. The sequence $(i)$ $NaOH$,(ii) $CO_2, \Delta, P$,(iii) $H^+/H_2O$,(iv) $(CH_3CO)_2O$ is the Kolbe-Schmitt reaction followed by acetylation,which yields aspirin. Thus,$C$ is aspirin.$4$. Reaction with $PhN_2Cl$ in $NaOH$ gives $p$-hydroxyazobenzene. The structure $D$ shown is $p$-aminoazobenzene,which is incorrect.Therefore,the correct matches are $A$,$B$,and $C$.

Column-$I$ (Reaction)	Column-$II$ (Condition)
$(A)$ $CH_3-CH(OH)-CH_3 \rightarrow CH_3-CH=CH_2$	$(i)$ $20\% \ H_3PO_4, 358 \ K$
$(B)$ $CH_3-C(CH_3)_2-OH \rightarrow CH_3-C(CH_3)=CH_2$	(ii) $Cu, 573 \ K$
$(C)$ $CH_3CH_2OH \rightarrow CH_2=CH_2 + H_2O$	(iii) $85\% \ H_3PO_4, 440 \ K$
$(D)$ $R-CH(OH)-R' \rightarrow R-CO-R'$	(iv) $H_2SO_4, 443 \ K$

The correct match about the reaction sequence shown above is:
