Write the reaction equation: CH2 = CH-CH2-CH2-CH2-CH3

CH2 = CH-CH2-CH2-CH2-CH3

The IUPAC nomenclature must be used for the name of this substance. If we have a double bond (=), and it is one, then the substance belongs to the class of alkenes, then the ending will be -en. The hydrocarbon chain is not branched, so we count by the amount of carbon. We have 6 carbon, so the name starts with hexa. The double bond is located at the first carbon, therefore there will be 1 at the end.

Substance name: hexene-1.
