select the correct answer. which hydrocarbon is an unsaturated hydrocarbon? a. 2 - methylheptane b. 3 - ethylpentane c. 1 - hexene d. cyclopentane

Answer

Answer:

C. 1 - hexene

Explanation:

Step1: Define saturated and unsaturated hydrocarbons

Saturated hydrocarbons have only single - C - C bonds. Unsaturated hydrocarbons have double or triple C - C bonds.

Step2: Analyze each option

A. 2 - methylheptane is an alkane with only single C - C bonds, so it is saturated. B. 3 - ethylpentane is an alkane with only single C - C bonds, so it is saturated. C. 1 - hexene is an alkene with a carbon - carbon double bond (C = C), so it is unsaturated. D. Cyclopentane is a cycloalkane with only single C - C bonds, so it is saturated.
