(a) $\mathrm{A} \rightarrow \mathrm{Q} ; \mathrm{B} \rightarrow \mathrm{S} ; \mathrm{C} \rightarrow \mathrm{R}$
(b) $\mathrm{A} \rightarrow \mathrm{R}, \mathrm{B} \rightarrow \mathrm{Q} ; \mathrm{C} \rightarrow \mathrm{P}$
(c) $\mathrm{A} \rightarrow \mathrm{R} ; \mathrm{B} \rightarrow \mathrm{S} ; \mathrm{C} \rightarrow \mathrm{Q}$
(d) $\mathrm{A} \rightarrow \mathrm{Q} ; \mathrm{B} \rightarrow \mathrm{S} ; \mathrm{C} \rightarrow \mathrm{P}$

(c)
(b)
Show Answer
Solution:
- The correct match is :
$\mathrm{A} \rightarrow(\mathrm{Q}) ;(\mathrm{B}) \rightarrow(\mathrm{S})(\mathrm{C}) \rightarrow(\mathrm{P})$
(A) Ester test confirms the presence of $-\mathrm{COOH}$ group.
(B) Carbylamine test confirms the presence of $-\mathrm{NH}_{2}$ group $\left(1^{\circ}\right)$.
(C) Phthalein dye test confirms the presence of phenolic - OH group.
