Vedclass · Answer

(A) $HCOOH$ (methanoic acid) acts as a reducing agent because it contains an aldehydic group $(-CHO)$ in its structure. It reduces ammoniacal silver nitrate solution (Tollen's reagent) to metallic silver,forming a silver mirror. $CH_3COOH$ (ethanoic acid) does not contain an aldehydic group and therefore does not reduce Tollen's reagent. Thus,Tollen's reagent can be used to distinguish between them.

The reagent that can be used to distinguish between methanoic acid and ethanoic acid is
