Q. In which of the following reactions, hydrogen is acting as an oxidising agent?
A) With Li to form LiH
B) With $I_{2}$ to give HI
C) With S to give $H_{2}S$
D) None of the above
Explanation
(a)
_{0 +1 -1}
$Li + H_{2} \longrightarrow 2LiH$
Oxidation number of hydrogen is decreasing from 0 to $- 1.$ So, $H_{2}$ is acting as oxidising agent in this reaction.
