Question

Which among the above compund/s does/do not form Silver mirror when treated with Tollen's reagent ?

• A. Only (II)
• B. (I), (III) and (IV) only
• C. (III) and (IV) only
• D. Only (IV)

Answer 1

The correct option is A Only (II)

Compounds having aldehyde group gives silver mirror test with Tollen's reagent.

(I) has aldehyde group.
(III) can tautomerise to aldehyde group so it gives silver mirror test.

Compound (IV)


Compound (II) tautomerise to ketone which does not give silver mirror test.
Hence, option (d) is the correct answer.
