Hydrocarbons that have one or more double or triple bonds are a. unsaturated b. saturated c. aromatic d. substituted

A. unsaturated

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms. The general formula for these hydrocarbons is

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

Aromatic hydrocarbons are those hydrocarbons in which Huckel's rule is obeyed. Example: Benzene

Substituted hydrocarbons are those hydrocarbons in which hydrogen is replaced by some other element. Example:
