The distinguishing test between methanoic acid and ethanoic acid is
- A Litmus test
- B Tollen'stest
- C Esterification test
- D Sodium bicarbonate test
Answer & Solution
Correct Answer
(B) Tollen'stest
Step-by-step Solution
Detailed explanation
Formic acid contains a hydrogen atom attached to carbonyl carbon like an aldehyde \( H-\stackrel{o}{C}- \), therefore, like aldehydes it reduces Tollens' reagent, but ethanoic acid is a true carboxylic acid which does not \( H-\stackrel{\|}{C}- \) group, hence cannot reduces Tollens' reagent.
