Answer

  1. Reduction
  2. Oxidation
  3. Oxidation
  4. Neither

Step by step solution

01

Oxidation and Reduction

The addition of oxygen or removal of hydrogen is an oxidation reaction.

The addition of hydrogen or removal of oxygen is a reduction reaction.

In an organic molecule, the addition of a C-O bond or removal of a C-H bond shows oxidation, and the addition of a C-H bond or removal of a C-O bond shows a reduction.

02

Identification of oxidation and reduction reaction

a.

Reduction reaction

The product molecule has one C-O bond less and one C-H bond more than the reactant molecule.

Therefore, the reaction is reduction.

b.

Oxidation reaction

The product molecule has one C-O bond more than the reactant molecule.

Therefore, the reaction is oxidation.

c.

Oxidation reaction

The product molecule has one C-O bond more and one C-H bond less than the reactant molecule.

Therefore, the reaction is oxidation.

d.

Addition reaction

In the product molecule, one C-H and one C-Cl bond are added. Therefore, the reaction is neither oxidation nor reduction.
