Question

In which type of chemical reaction are electrons transferred?

1) organic addition
2) oxidation-reduction
3) double replacement
4) acid-base neutralization

Answer 1

Answer: It is number 2

Answer 2

The correct answer is 2.

In oxidation-reduction reactions (or redox reactions), a number of electrons are transferred between two species. During this process, the oxidation number of an atom (or molecule or ion) changes by receiving or losing an electron.
