Question
Assertion:
Hydrogen bonding in carboxylic acids is stronger than alcohols.
Reason:
Highly branched carboxylic acids are more acidic than unbranched acids.
Solution
The assertion and the reason are not directly related.
Assertion: Hydrogen bonding in carboxylic acids is stronger than in alcohols. This is true because carboxylic acids have two polar sites (C=O and -OH) and can form two hydrogen bonds, while alcohols only have one polar site (-OH) and can form only one hydrogen bond.
Reason: Highly branched carboxylic acids are more acidic than unbranched acids. This is also true, but it's due to the fact that branching in carboxylic acids increases the stability of the carboxylate ion, making the acid more likely to donate a proton and thus increasing its acidity.
However, the reason doesn't explain the assertion. The strength of hydrogen bonding in carboxylic acids vs alcohols is a separate issue from the effect of branching on the acidity of carboxylic acids.
