Question

Categorize each hydrocarbon as being saturated or unsaturated.

- 3-methyloctane (___________)


- cyclopentene (___________)


- propane (___________)


- heptyne (___________)


- heptane (___________)

Answer 1

Saturated hydrocarbons have only single bonds between carbon atoms, while unsaturated hydrocarbons have double or triple bonds. 3-methyloctane, propane, and heptane are saturated hydrocarbons, while cyclopentene and heptyne are unsaturated hydrocarbons.

Step-by-step explanation:

The hydrocarbons can be categorized as saturated or unsaturated based on the presence of double or triple bonds between carbon atoms. Saturated hydrocarbons contain only single bonds between carbon atoms, while unsaturated hydrocarbons have at least one double or triple bond.

1. 3-methyloctane: This hydrocarbon does not have any double or triple bonds and is composed of single bonds between carbon atoms. Therefore, it is a saturated hydrocarbon.
2. cyclopentene: This hydrocarbon contains a double bond between carbon atoms. Therefore, it is an unsaturated hydrocarbon.
3. propane: This hydrocarbon does not have any double or triple bonds and is composed of single bonds between carbon atoms. Therefore, it is a saturated hydrocarbon.
4. heptyne: This hydrocarbon contains a triple bond between carbon atoms. Therefore, it is an unsaturated hydrocarbon.
5. heptane: This hydrocarbon does not have any double or triple bonds and is composed of single bonds between carbon atoms. Therefore, it is a saturated hydrocarbon.
