$HCOOH$ and $CH_3COOH$

Vedclass · Answer

(C) The pair of molecules that forms the strongest intermolecular hydrogen bonds is formic acid $(HCOOH)$ and acetic acid $(CH_3COOH)$.Hydrogen bonding occurs between a hydrogen atom covalently bonded to a highly electronegative atom ($N$,$O$,or $F$) and another electronegative atom with a lone pair.In the case of carboxylic acids like $HCOOH$ and $CH_3COOH$,they form stable cyclic dimers through two intermolecular hydrogen bonds.These dimers are exceptionally stable due to the resonance-stabilized structure of the carboxylate group,making the hydrogen bonds in these carboxylic acid pairs stronger than those found in $H_2O$ or $H_2O_2$.

The strongest intermolecular hydrogen bond is present in which of the following pairs of molecules?
