MCQ
Strong reducing behaviour of $H_3PO_2$ is due to
  • A
    High oxidation state of phosphorus
  • B
    Presence of two $-OH$ groups and one $P-H$ bond
  • ✓
    Presence of one $-OH$ group and two $P-H$ bonds
  • D
    High electron gain enthalpy of phosphorus
✓

Answer

Correct option: C.
Presence of one $-OH$ group and two $P-H$ bonds
c
Strong reducing behaviour of $\mathrm{H}_{3} \mathrm{PO}_{2}$.

All oxy-acid of phosphorus which contain $\mathrm{P}-\mathrm{H}$ bond act as reductant.

presence of one - $\mathrm{OH}$ group and two $\mathrm{P}-\mathrm{H}$ bonds
