Answer: 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 [tex]C_nH_{2n+2}[/tex]
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 [tex]C_nH_{2n}[/tex] and [tex]C_nH_{2n-2}[/tex]
Aromatic hydrocarbons are those hydrocarbons in which Huckel's rule [tex](2n+2)\pi[/tex] is obeyed. Example: Benzene
Substituted hydrocarbons are those hydrocarbons in which hydrogen is replaced by some other element. Example: [tex]CH_3Cl[/tex]
