Total number of compounds among the following which will give positive Tollen's reagent test is:
`CH_(3) - CH_(2) - OH C _(6) H _(5) COH `
`CH _(3) CHO`
`CH_(3) - overset(O) overset(||) (C) - CH_(3) " " C _(6) H _(5) COOH`
` CH_(3) CH_(2) CHO`

Text Solution

Verified by Experts

The correct Answer is:
3
Both aliphatic and aromatic aldehydes gives positive Tollen.s reagent test (silver mirror test).
`C_(6) H_(5) CHO, CH_(3) CHO and CH _(3) CH_(2) CHO` give this test.
