Q.
Of the following acids
I: hypo phosphorous acid
II: hydrofluoric acid
III: oxalic acid
IV: glycine
The p-Block Elements
Solution:
I. $H _2 PO _2$ is monobasic acid forming $NaH _2 PO _2$
II. $H _2 F _2$ forms two series of salts $KHF _2$ and $K _2 F _2$
Thus, dibasic acid
III. $H _2 C _2 O _4$ is dibasic acid
