Question

Carboxylic acids boil at considerably higher temperatures than do alcohols, ketones, or aldehydes of similar molecular weights. This is because they: A. have a greater oxygen content. B. are more acidic. C. form stable hydrogen-bonded dimers. D. are hydrophobic. E. none of the above

Answer 1

The correct option is: C. form stable hydrogen-bonded dimers

Step-by-step explanation:

Boiling point is the temperature at which a particular substance changes from liquid state to vapor state.

The boiling point of a chemical substance depends upon the intermolecular forces present between the molecules.

Carboxylic acids are the organic molecules containing carboxyl functional group (COOH). They tend to have greater boiling point than alcohols, ketones, or aldehydes.

This is because only carboxylic acids are capable of forming dimers that are stabilized by hydrogen bonding.
