Strong reducing behaviour of H3PO2 is due to
Strong reducing behaviour of H3PO2 is due to

(i) The low oxidation state of phosphorus

(ii) Presence of two –OH groups and one P–H bond

(iii) Presence of one –OH group and two P–H bonds

(iv) High electron gain enthalpy of phosphorus

 

Correct Answer: (iii) Presence of one –OH group and two P–H bonds

Explanation: Strong reducing behaviour of H3PO2 is due to the presence of one –OH group and two P–H bonds.
