Question

Which of the following is an example of reduction?

• A.
• B. + 2
• C.
• D.

Answer 1

The correct option is A

Do you remember the electronic concept of reduction.

Reduction : It is a process in which an atom or a group of atoms taking part in a chemical reaction gains one or more electrons. For example:

$C{l}_2+2e^{-}⟶2C{l}^{-}$

Therefore, for option (a) there is gain of electrons and hence reduction.
