Answer 1

Reactions, in which a compound undergoes both oxidation and reduction simultaneously, are called disproportionation.

White phosphorus reacts with caustic soda. The products are phosphine $P H_{3}$ and sodium hypophosphite $N a H_{2} P O_{2}$ . This reaction is an example of disproportionation.

$P_{4} + 3 N a O H + 3 H_{2} O ⟶ 3 N a H_{2} P O_{2} + P H_{3}$

Option (D) is correct.

Answer 2

Reactions, in which a compound undergoes both oxidation and reduction simultaneously, are called disproportionation.

White phosphorus reacts with caustic soda. The products are phosphine

P H_{3}

and sodium hypophosphite

N a H_{2} P O_{2}

. This reaction is an example of disproportionation.

P_{4} + 3 N a O H + 3 H_{2} O ⟶ 3 N a H_{2} P O_{2} + P H_{3}

Option (D) is correct.
