Vedclass · Answer

(B) $1$. Ethanol $(C_2H_5OH)$ is a primary alcohol,while formic acid $(HCO_2H)$ is a carboxylic acid with an aldehyde-like group $(-CHO)$.$2$. Tollen's reagent,Fehling solution,and $HgCl_2$ solution are oxidizing agents that react with the $-CHO$ group present in formic acid to give positive tests (e.g.,silver mirror,red precipitate,or white precipitate),whereas ethanol does not react with these reagents.$3$. Hot acidic $KMnO_4$ solution is a strong oxidizing agent that oxidizes both ethanol (to acetic acid) and formic acid (to $CO_2$ and $H_2O$).$4$. Since both compounds react with hot acidic $KMnO_4$,this reagent cannot be used to distinguish between them.

Ethanol $(C_2H_5OH)$ and formic acid $(HCO_2H)$ cannot be distinguished by:
