Question

What is the C Double bond called?

Answer 1

Types of hydrocarbon:

Hydrocarbons are classified into two classes Saturated hydrocarbons and Unsaturated hydrocarbons.

• Saturated hydrocarbons include those hydrocarbons which have only single bonds between carbon-carbon$(\mathrm{C}-\mathrm{C})$ atoms and these compounds are known as alkanes.

Unsaturated hydrocarbons include those hydrocarbons which have one or more than one multiple bonds between carbon-carbon atoms.

• Alkenes are those unsaturated hydrocarbons that contain at least one carbon-carbon double bond$(\mathrm{C}=\mathrm{C})$. Example: Ethene ${\mathrm{CH}}_2={\mathrm{CH}}_2$'
• Alkynes are those unsaturated hydrocarbons that contain at least one carbon-carbon triple bond. Example: Ethyne $\mathrm{CH}\equiv \mathrm{CH}$

Hence, C double bond is called Alkenes.
