Answer :
Answer: The given compound is 1-butene.
Explanation:
In simple hydrocarbons, if there are only single bonds present then the suffix "ane" is added to the name of hydrocarbon.
If there is a double bond then suffix "ene" is added to the name.
If there is a triple bond then suffix "yne" is added to the name.
For example, [tex]CH_{2}=CH_{2}-CH_{2}-CH_{3}[/tex] has one double bond which is at position 1 and there are four carbon atoms present.
Hence, name of this compound is 1-butene.
