Question

A saturated hydrocarbon will undergo _________ reactions whereas the typical reaction of an unsaturated hydrocarbon is ______

• A. Substitution reaction
• B. Addition reaction

Answer 1

• A saturated hydrocarbon consists of a single bond in which each bond is attached to an atom, and is highly stable, due to which there is no possibility for the addition of another atom, for example; Ethane ($C_2{H}_6$).
• Thus, saturated hydrocarbons undergoes substitution reaction.
• Whereas unsaturated hydrocarbon consists of double or triple bonds in which two or three bonds are attached to the same atom, which has 1 or 2 pi ($\mathrm{\pi }$) bonds that are unstable and can be broken easily.
• Thus, unsaturated hydrocarbons undergo an addition reaction. Example; Ethyne ($C_2{H}_4$).
