Question

Ammonia on reaction with hypochlorite anion can form :
(a) NO
(b) N₂H₄
(c) NH₄Cl
(d) Both (b) and (c)

Answer 1

Ammonia ,NH3, reacts with hypochlorite anion OCl-, to produce hydrazine,N2H4.

2NH3+OCl- ----> N2H4

Answer 2

Answer:

The correct is (d). Both N2H4 and NH4Cl are formed when ammonia reacts with hypochlorite ion.

Explanation:

• The reactions leading to the formation of N2H4 and NH4Cl are:

1. NH3 + HOCl-----> NH4Cl+H2O
2. 2NH3 + OCl- ----> N2H4 + Cl- +H2O

• OCl- is the hypochlorite anion.
• Upon the reaction of hypochlorite ion with ammonia forms hydrazine (N2H4).
• Chloramine formed in the reaction decomposes hydrazine into NH4Cl.
