Answer:
The correct answer is :It is a molecule composed of carbon and hydrogen only.
Explanation:
Hydrocarbons are defined as compounds which majorly made up carbon and hydrogen.There three types of hydrocarbons:
- Alkanes : These are saturated hydrocarbons with single bond present in between two carbon atoms.The general structure of an alkane is:[tex]C_nH_{2n+2}[/tex]
- Alkene :These are unsaturated hydrocarbons with double bond present in between two carbon atoms.The general structure of an alkene is:[tex]C_nH_{2n}[/tex]
- Alkyne :These are unsaturated hydrocarbons with triple bond present in between two carbon atoms.The general structure of an alkyne is:[tex]C_nH_{2n-1}[/tex]
