Consider the reaction of lithium with nitrogen. What is the product formed and what is its nature upon hydrolysis?

A. Li_3 N, which produces ammonia on hydrolysis. — Lithium reacts directly with nitrogen to form lithium nitride, which undergoes hydrolysis to yield lithium hydroxide and ammonia.

B. LiN_3, which produces hydrazoic acid on hydrolysis.

C. Li_3 N_2, which produces nitrogen gas on hydrolysis.

D. LiN, which produces nitric acid on hydrolysis.

$Consider the reaction of Li with N_{2} . What is the product formed and what is its nature upon hydrolysis?$

A. $Li_{3} N, which produces ammonia on hydrolysis.$
B. $LiN_{3}, which produces hydrazoic acid on hydrolysis.$
C. $Li_{3} N_{2}, which produces nitrogen gas on hydrolysis.$
D. $LiN, which produces nitric acid on hydrolysis.$

Show correct answer & step-by-step solution

Correct answer: A — $Li_{3} N, which produces ammonia on hydrolysis.$

Solution

$Lithium is the only alkali metal that reacts directly with N_{2} at room temperature to form Li_{3} N .$
$The hydrolysis reaction is Li_{3} N + 3 H_{2} O \to 3 LiOH + NH_{3} .$
$Hence the answer is (A).$
