(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.

Of an acetal?arrow_forward16-28 Following is the structural formula of metformin, the hydrochloride salt of which is marketed as the antidiabetic medication Glucophage. Metformin was introduced into clinical practice in the United States in 1995 for the treatment of type 2 diabetes. More than 25 million prescriptions for this drug were written in 2000, making it the most commonly prescribed brand-name diabetes medication in the nation.
