(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.
(b)
Interpretation:
With help of a chemical test distinguish between cyclohexene and cyclohexanone.
Concept Introduction:
Cyclohexene is an
(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.
