Oxidation reactions constitute reactions where the atom or ion is deprived of one or several electrons. The molecule that acquires electrons is termed the oxidizing agent.

Reduction reactions constitute reactions where the atom or ion acquires one or several electrons. The reaction between copper oxide and magnesium to generate copper and magnesium oxide is a reduction reaction.

(a)The reaction of compound a can be given as:

Reaction of compound a

Hence, the given reactions are oxidation reactions.

b)

Reaction of compound b

The given reactions can be sequenced as: oxidation, oxidation, reduction, oxidation

(c)The reaction of compound c can be given as:

In this reaction the first carbon is oxidized and the third carbon is reduced.

The given reaction is neither oxidation or reduction.

(d)The reaction of compound d can be given as:

Reaction of compound d

The given reaction is a reduction reaction as the loss of oxygen happens in this reaction.

(e)The reaction of compound e can be given as:

Reaction of compound e

The given reaction is an oxidation reaction.

(f)

Reaction of compound f

(g)The reaction of compound g can be given as:

Reaction of compound f

The reaction undergoes neither oxidation or reduction due to the addition of HBr.

(h)The reaction of compound h can be given as:

The loss of water molecule makes the reaction to be neither oxidation or reduction in the first step. The second step is a reduction reaction due to the addition of hydrogen atom.

Reaction of compound j

The first reaction is an oxidation reaction. The second step involves the addition of water molecule, so it is neither oxidation or reduction.

(k)The reaction of compound k can be given as:

Reaction of compound k

The given reaction is an oxidation reaction.

(l)The reaction of compound l can be given as:

Reaction of compound l

The reaction undergoes oxidation in the first step and reduction in the second step.
