Question

Which of the following pairs of organic compounds give positive Tollens’ test? (A) Formic acid, acetone (B) Formic acid, ethanal (C) Ethanal, acetone (D) Formic acid, acetic acid

Tardigrade Admin · Accepted Answer

Both aliphatic and aromatic aldehyde reduce Tollens’ reagent. The only carboxylic acid i.e., Formic acid reduces Tollens’ reagent as it contains both aldehyde (-CHO) as well as carboxyl group (-COOH)
