Question

Reason
One H-atom is non-ionizable in more stable tautomeric form of $$H_{3}PO_{3}.$$
Assertion
In $$H_{3}PO_{3},$$ basicity of the oxy acid is two.

A
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
B
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
C
Assertion is correct but Reason is incorrect
D
Both Assertion and Reason are incorrect
Solution
Verified by Toppr

Correct option is A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In more stable structure (B) one H-atom is non-ionizable hence its basicity is $$2$$.

Hence, Option "A" is the correct answer.
