Question

Some qualitative tests are given below

Test	Inference
(I) dll HCI	Insoluble
(II) NaOH	soluble
(III) $Br_2$/water	decolorised

The compound(s) below, which do(es) not give all three tests is/are

• A. A. Cyclohexanol
• B. B. Phenol
• C. C. Aniline
• D. D. Cyclohexylamine

Answer 1

Answer: (A), (C), (D)

A, C, and D

Answer 2

• Cyclohexanol: Insoluble in NaOH (fails test II) and does not decolorize Br$_2$/water (fails test III).
• Phenol: Soluble in dil HCl (passes test I), soluble in NaOH (passes test II), and decolorizes Br$_2$/water (passes test III).
• Aniline: Soluble in dil HCl (fails test I) and insoluble in NaOH (fails test II).
• Cyclohexylamine: Soluble in dil HCl (fails test I), insoluble in NaOH (fails test II), and does not decolorize Br$_2$/water (fails test III).

Compounds A, C, and D do not give all three tests.
