Assertion : The carbonic acid is stronge...

Assertion : The carbonic acid is stronger acid than phenol .
Reason : The hybrid of bicarbonate ion has two equivalent contributing structures, while hybrid of phenoxide ion does not contain such equivalent contributing structures.

A

If both the assertion and reason are true statement and reason is correct explanation of the assertion .

B

If both the assertion and reason are true statement but reason is not a correct explanation of the assertion .

C

If the assertion is true but the reason is a false statement.

D

If both assertion and reason are false statements.

Text Solution

Verified by Experts

The correct Answer is:
A

The phenoxide ion `C_(6)H_(5)--O^(-)` , does not have any contributing structure but `HCO_(3)^(-)` ion has two contributing structure , that is why `H_(2)CO_(3)` is stronger acid than `C_(6)H_(5)OH`
