Chapter 16, Problem 55P

Interpretation Introduction

(a)

Interpretation:

With help of a chemical test distinguish between cyclohexanone and aniline.

Concept Introduction:

Cyclohexanone and aniline both are insoluble in water. Distinction between them by a test is based on the fact that cyclohexanone is neutral to both acids and bases while aniline is a weak base and reacts with acid.

Interpretation Introduction

(b)

Interpretation:

With help of a chemical test distinguish between cyclohexene and cyclohexanone.

Concept Introduction:

Cyclohexene is an unsaturated hydrocarbon and shows the positive unsaturation test.

Interpretation Introduction

(c)

Interpretation:

With help of a chemical test distinguish between benzaldehyde and cinnamaldehyde.

Concept Introduction:

Benzaldehyde and cinnamaldehyde are distinguished by a test which is based on the fact that cinnamaldehyde has carbon-carbon double bond. Cinnamaldehyde gives unsaturation test while benzaldehyde does not give this test.
