Question

Tell whether each of the following reactions is an oxidation, a reduction, or neither:

Short answer

It is a reduction reaction.

Step-by-step solution

Oxidation reaction

Oxidation means loss of electrons in a reaction. Oxidation occurs when the oxidation state is increased.

Reduction reaction

Reduction means the gain of electrons or oxidation state is decreased. Removal of the electronegative atoms is reduction.

 Step 3: Reaction interpretation

In this reaction bromine, an electronegative atom is getting removed and hydrogen is getting attached. It is a reduction reaction.
