The molecule that functions as the reducing agent (electron donor) in a redox or oxidation-reduction reaction _____.
1 answer:
Answer : The correct option is a) Loses electrons and loses potential energy.
Explanation :
Reducing agent : In a redox reaction, it is oxidized by the loss of electrons and by the loses of potential energy. It is also called as electron donor.
Reducing agent reduces others by loss of electron and its oxidation state increases.
For example : Sodium is a reducing agent and itself oxidized as follows,
Therefore, the molecule that function as a reducing agent in a redox reaction is loses electrons and loses potential energy.

A free-radical substitution reaction is likely to be responsible for the observations. The reaction mechanism of a reaction like this can be grouped into three phases:
- Initiation; the "light" on the mixture deliver sufficient amount of energy such that the halogen molecules undergo homologous fission. It typically takes ultraviolet radiation to initiate fissions of the bonds.
- Propagation; free radicals react with molecules to produce new free radicals and molecules.
- Termination; two free radicals combine and form covalent bonds to produce stable molecules. Note that it is possible for two carbon-containing free-radicals to combine, leading to the production of trace amounts of long carbon chains in the product.
