3-methyloctane and propane are saturated hydrocarbon. Cyclopentene, heptyne and propyne are unsaturated hydrocarbon.
Explanation:
Saturated hydrocarbons may be defined as hydrocarbons containing only single bonds. Unsaturated hydrocarbons contains double and triple bonds in its structure.
The hydrocarbons -3- methyl octane and propane contains only single bonds within carbon and hydrogen. These saturated hydrocarbons are commonly named as alkanes. Cyclopentene, heptyne and propyne are unsaturated hydrocarbons as they contains double and triple bonds. Cyclopenetene contains double bond and commonly named as alkenes. Heptyne and propyne has three vbonds in its structure and are referred as alkynes.
Saturated means that the hydrocarbon has only single bonds and that the hydrocarbon contains the maximum number of hydrogen atoms for each carbon atom. Unsaturated hydrocarbons contain multiple bonding and contain less than the maximum number of hydrogen per carbon.
Saturated hydrocarbon is 3-methyloctane, and propane.
Unsaturated hydrocarbon is Propyne, heptyne, cyclopentene.
