Question

explain the different type of redox reactions with example
​

Answer 1

Answer:

A reaction in which one reactant undergoes oxidation whereas the other gets reduced during the course of reaction are termed as oxidation-reduction reactions or redox reactions. Oxidation refers to the loss of electrons or increase in oxidation state by a molecule, atom, or ion.

Redox reactions are matched sets: if one species is oxidized in a reaction, another must be reduced. Keep this in mind as we look at the five main types of redox reactions: combination, decomposition, displacement, combustion, and disproportion

Answer 2

Answer:

Decomposition Reaction

Combination Reaction

Displacement Reaction

Double displacement Reactions

Disproportionation Reactions

Explanation:

Redox reactions are reactions where oxidation and reduction take place simultaneously due to exchange of electrons. in decomposition reactions, one reactant breaks down into multiple products eg:2H2O → 2H2 + O2.

in a combination reaction, multiple reactants combine to create one product. eg: 4Fe+ 3O2→2Fe2O3

in a displacement one ion of a compound with a higher reactivity displaces the ion of the compound it reacts with. eg: CuSO4+Zn→Cu+ZnSO4

in a double displacement reaction, the ions of two compounds are exchanged eg: CuCl 2(aq) + 2 AgNO 3(aq) → Cu(NO 3) 2(aq) + 2 AgCl(s)

The reactions in which single reactant is oxidized and reduced is known as Disproportionation reactions.

For example: P4 + 3NaOH + 3H2O → 3NaH2PO2 + PH3

hope this helps :)
