$I > II > III > IV$

Vedclass · Answer

(A) The acidic strength of carboxylic acids is inversely proportional to the $+I$ (inductive) effect of the alkyl group attached to the $-COOH$ group.As the number of carbon atoms in the alkyl chain increases,the $+I$ effect increases,which destabilizes the carboxylate ion and decreases the acidic strength.The order is:$I$ (Methanoic acid,$H-COOH$) > $II$ (Ethanoic acid,$CH_3-COOH$) > $III$ (Propanoic acid,$CH_3CH_2-COOH$) > $IV$ (Butanoic acid,$CH_3CH_2CH_2-COOH$)Therefore,the correct order is $I > II > III > IV$.

What is the decreasing order of acidic strength for the following acids?
$[I]$ Methanoic acid
$[II]$ Ethanoic acid
$[III]$ Propanoic acid
$[IV]$ Butanoic acid
