Assertion: Carboxylic acids have greater boiling point than...
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 (\rightarrow) True.
Carboxylic acids show stronger intermolecular forces than alcohols.
- Reason: Carboxylic acids can form dimers in solution (\rightarrow) 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 reason is the correct explanation of the assertion.
