Question
What is the basicity of H3PO2 acid and why?
Solution
Basicity of H3PO2 depends on upon the number of ionizable -OH groups present in the molecule. That is the number of hydrogen attached to the electronegative atom oxygen.
H3PO2 has one ionizable –OH group, thus its basicity is 1.
The structure of H3PO2 is as follows:
