Question

Differentiate between addition reactions and substitution reactions shown by hydrocarbons.

Answer 1

substitution reaction and addition reaction

Answer 2

Dear Student,

◆ Addition reactions -

• In addition reaction, two or more substances combine to form a single substance.
• Typically unsaturated hydrocarbons are converted to saturated hydrocarbons by addition of hydrogen.
• For example, hydrogenation reactions of acetylene.

◆ Substitution reactions -

• In substitution reaction, one functional group of compound is replaced by another group.
• Typically hydrogen atom of saturated hydrocarbon is replaced by other functional group.
• For example, halogenation of ethane.

Thanks dear...
