Question

The reaction of white phosphorus on boiling with alkali in inert atmosphere resulted in the formation of product A. The reaction 1 mol of A with excess of  in aqueous medium gives  mole(s) of Ag. (Round off to the Nearest Integer).

Canvas Classes · Accepted Answer

White phosphorus + NaOH:

A =  → acid form =  (hypophosphorous acid, phosphinic acid)

has 2 P–H bonds and is a strong reducing agent.

Reaction with :

Wait — P goes from +1 to +5 (loses 4 electrons), so 4 Ag should be reduced.

Actually: : P: +1 → +5, change = 4e⁻
