Question

Reduction never involves:

• A. Gain of electrons
• B. Decrease in oxidation number
• C. Loss of electrons
• D. Decrease in valency of electropositive component

Answer 1

The correct option is C Loss of electrons

When substance undergoes reduction there will be gain of electrons and decrease in oxidation number. As substance gained electrons so there will be decrease in valency of electropositive element.

But during reduction substance never undergoes loss of electrons.
