Question

A reaction in which oxidation and reduction take place simultaneously is known as:

• A. (A) Oxidation reaction
• B. (B) Reduction reaction
• C. (C) Hydrogention reaction
• D. (D) Redox reaction

Answer 1

The correct option is D

(D) Redox reaction

The explanation for the correct option

Option (D). Redox Reaction.

Redox reaction:

• Red means reduction and Ox means oxidation.
• Oxidation and reduction take place simultaneously
• Oxidising and reducing agents will be present.

The explanation for the incorrect option

Option (A). Oxidation

• When a substance adds oxygen to it or eliminates hydrogen from it, then the substance is oxidized. this process is known as oxidation.
• The substance that brings about oxidation is called the oxidizing agent.

Option (B). Reduction

• When a substance adds hydrogen to it or eliminates oxygen from it, then the substance is reduced. this process is known as reduction.
• The substance that brings about reduction is called the reducing agent.

Option (C). Hydrogenation

• It is an addition reaction between hydrogen and other compounds in the presence of a catalyst.
• Solid vanaspati is obtained by passing hydrogen gas through the oil in the presence of nickel as a catalyst. this process is called hydrogenation.

Hence, Option(D)is the correct option. i.e, Redox Reaction is the reaction in which oxidation and reduction take place simultaneously.
