Question

The oxoacid of phosphorus that is easily obtained from a reaction of alkali and white phosphorus and has two P-H bonds, is : (A) Phosphonic acid (B) Phosphinic acid (C) Pyrophosphorus acid (D) Hypophosphoric acid

Tardigrade Admin · Accepted Answer

P 4+3 NaOH +3 H 2 O arrow PH 3+3 NaH 2 PO 2 oxoacid = H 3 PO 2 (hypo phosphorus acid) or (phosphinic acid)

Q. The oxoacid of phosphorus that is easily obtained from a reaction of alkali and white phosphorus and has two $P - H$ bonds, is :

Phosphonic acid

Phosphinic acid

Pyrophosphorus acid

Hypophosphoric acid

$P_{4} + 3 N a O H + 3 H_{2} O \to P H_{3} + 3 N a H_{2} P O_{2}$
oxoacid $= H_{3} P O_{2}$ (hypo phosphorus acid) or (phosphinic acid)
