The distinguishing test between methanoic acid and ethanoic acid is
Options
- ALitmus test
- BTollen'stest
- CEsterification test
- DSodium bicarbonate test
Correct answer
B. Tollen'stest
Step-by-step solution
Formic acid contains a hydrogen atom attached to carbonyl carbon like an aldehyde ( H- o C - ), therefore, like aldehydes it reduces Tollens' reagent, but ethanoic acid is a true carboxylic acid which does not ( H- | C - ) group, hence cannot reduces Tollens' reagent.
