MCQ
Strong reducing behaviour of $H_3PO_2$ is due to
  • A
    low co-ordination number of phosphorus
  • B
    high oxidation state of phosphorus
  • C
    presence of two $-OH$ groups and one $P-H$ bond
  • ✓
    presence of one $-OH$ group and two $P-H$ bonds.
✓

Answer

Correct option: D.
presence of one $-OH$ group and two $P-H$ bonds.
d
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 -OH group and two $P-H$ bonds
