Question

Assertion (A): Elements with greater electron affinities are better oxidizing agents.

Reason (R): Oxidation is the gaining of electrons.

• A. Both A and R are true and R is the correct explanation of A.
• B. Both A and R are true, but R is not the correct explanation of A.
• C. A is true and R is false.
• D. A is false and R is true.

Answer 1

The correct option is C

A is true and R is false.

Explanation for Assertion statement:

1. The oxidizing agent is a chemical species that conducts a chemical process in which it obtains one or more electrons.
2. As a result, they have a high probability to gain an electron, making them a powerful oxidizer.

Explanation for Reason statement:

1. Oxidation is the loss of electrons.
2. The loss of electrons by a molecule, atom, or ion during a reaction is known as oxidation.
3. When the oxidation state of a molecule, atom, or ion is increased, oxidation occurs.

A is true and R is false. Hence option C is correct.
