NEETChemistryCarboxylic Acid Derivatives
Assertion: Carboxylic acids have greater boiling point than alcohols. Reason: Carboxylic acids have the ability to form dimers in solution.
Options
- ABoth assertion and reason are correct statements, and reason is the correct explanation of the assertion.
- BBoth assertion and reason are correct statements, but reason is not the correct explanation of the assertion.
- CAssertion is correct, but reason is wrong statement.
- DAssertion is wrong, but reason is correct statement.
Correct answer
A. Both assertion and reason are correct statements, and reason is the correct explanation of the assertion.
Step-by-step solution
- Assertion: Carboxylic acids have greater boiling point than alcohols ( ) True. Carboxylic acids show stronger intermolecular forces than alcohols. - Reason: Carboxylic acids can form dimers in solution ( ) True. They form cyclic dimers via two hydrogen bonds between two - COOH groups. This dimerization effectively doubles molecular mass and strengthens intermolecular attraction. - Since the reason correctly explains the assertion, the correct answer is: (a) Both assertion and reason are correct statements, and re
