(B) Benzaldehyde & & (Q) Tollen's reagent
(C) Phenol & & (R) Lucas reagent
(D) Isopropanol & & (S) Phthalein dye test
\endtabular \endcenter

• A. A-P, B-Q, C-S, D-R
• B. A-R, B-S, C-Q, D-P
• C. A-S, B-R, C-P, D-Q
• D. A-P, B-R, C-Q, D-S

Answer 1

The Correct Option is A

Concept: Different functional groups give characteristic qualitative tests with specific reagents.
Step 1: Aniline Primary amines react with Hinsberg reagent (benzenesulfonyl chloride) to give sulfonamide derivatives. \[ \text{Aniline} \rightarrow \text{Positive Hinsberg test} \] \[ A \rightarrow P \]
Step 2: Benzaldehyde Aldehydes reduce Tollen’s reagent forming a silver mirror. \[ \text{Benzaldehyde} \rightarrow \text{Positive Tollen's test} \] \[ B \rightarrow Q \]
Step 3: Phenol Phenols give a positive phthalein dye test. \[ C \rightarrow S \]
Step 4: Isopropanol Secondary alcohols give turbidity with Lucas reagent. \[ D \rightarrow R \]
Step 5: Final matching \[ A-P,\quad B-Q,\quad C-S,\quad D-R \]
