hydrogenation
addition
substitution
redox

Respuesta :

Answer: substitution

Explanation:

Hydrogenation is defined as a chemical reaction in which hydrogens are added to hydrocarbons using reducing agents.

[tex]C_2H_2+2H_2\rightarrow C_2H_6[/tex]

Addition reaction is defined as the reaction in which two reactants get added to give single product.

[tex]A+B\rightarrow AB[/tex]

Substitution reaction is defined as the reaction in which one atom replaces the other atom from the compound.

[tex]CH_4+Cl_2\rightarrow CH_3Cl+HCl[/tex]

Redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously. Oxidation reaction is defined as the reaction in which a substance looses its electrons.Reduction reaction is defined as the reaction in which a substance gains electrons.

[tex]M+N^+\rightarrow M^++N[/tex]
