Answer 1

Answer: (1)

Explanation: In chemistry, an alkene is a hydrocarbon containing a carbon-carbon double bond. Alkene is often used as a synonym of olefin, that is, any hydrocarbon containing one or more double bonds. Two general types of monoalkenes are distinguished: terminal and internal. Also called α-olefins, terminal alkenes are more useful.
