Problem: Tell whether each of the reactions below is an oxidation, reduction or neither.

FREE Expert Solution

Oxidation → gains an O atom or addition of an electronegative atom (increases oxidation state)

Reduction → loses an O atom or removal of an electronegative atom (decreases oxidation state)

Analyzing each reaction:

a. 

Notice that we produced -OH on the reactant side

This will be considered as oxidation


b. 

Br is being added on this reaction, where Br is an electronegative atom (Group 7A)
