Which of the following reagent/solution ...

Which of the following reagent/solution can be used to distinguish between methanoic acid and ethanoic acid?

A

Tolle's reagent

B

`FeCl_(3)` solution

C

`NaOH` solution

D

`NaCO_(3)` solution

Text Solution

Verified by Experts

The correct Answer is:
A
Due to the presence of -CHO group, methanoic acid (HCOOH) can reduce Tollen's reagent.
`HCOOH+Ag_(2) O to CO_(2) +H_(2) O+ underset("Silver mirror") (2Ag)`
But no-CHO group is present in ethanoic acid `(CH_(3)COOH)`, os it cannot reduce Tollen's reagent.
