Question

Which of the following reactions involving Lithium is highlighted as unique among alkali metals?
Options
A Reaction with oxygen to form a simple oxide (2Li₂O).
B Reaction with nitrogen to form nitride (2Li₃N).
Correct Answer
C Reaction with water to form lithium hydroxide (LiOH).
D Reaction with hydrogen to form lithium hydride (LiH).
Correct Answer

Option B is the correct answer.

Detailed Explanation

On page 6, it is stated that Lithium 'is the only alkali metal which can react with nitrogen to form nitride', showing the reaction: 6Li + N₂ → 2Li₃N.

Hint

Focus on the reactions mentioned as specific to lithium's anomalous behavior, particularly with atmospheric gases.
