Question

There is very little difference in acid strength in the series H3PO4,H3PO3 and H2PO2 because (A) Phosphorus in these acids exists in different oxidation states (B) Number of unprotonated oxygen responsible for increase of acidity due to inductive effect remains the same (C) Phosphorus is not a highly electronegative element (D) Phosphorus oxides are less basic.

There is little difference in the strength of these acids because phosphorous is not a highly electro-negative element, i.e., its oxides are less basic.

Q. There is very little difference in acid strength in the series H3​PO4​,H3​PO3​ and H2​PO2​ because

Phosphorus in these acids exists in different oxidation states

Number of unprotonated oxygen responsible for increase of acidity due to inductive effect remains the same

Phosphorus is not a highly electronegative element

Phosphorus oxides are less basic.

There is little difference in the strength of these acids because phosphorous is not a highly electro-negative element, i.e., its oxides are less basic.
