Which of the following is/are true? Hydrocarbons contain carbon, hydrogen and oxygen. Alkenes and Alkynes are unsaturated hydrocarbons. An alkane with 5 carbons has a molecular formula of C5H10. Hydrocarbons only contain C-C single bonds. More than one of above is true.

Alkenes and Alkynes are unsaturated hydrocarbons.

Explanation:

Hydrocarbons are compounds containing carbon and hydrogen.

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms.These are called as alkanes. The general formula for these hydrocarbons is . Thus alkane with 5 carbon atoms will have formula of

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is and respectively.
