By following similar steps to naming alkanes, but the suffix is -ene, the position of the double bond has to be stated if it has 4 or more carbons, and you use the smallest number for the position.

Describe a molecule of but-1-ene.
It has 4 carbons in the longest chain, it has a double bond between carbons 1 and 2, it's an alkene.

How do you separate numbers and words in organic compound names?
Separate numbers by commas and place hyphens between numbers and words.

What would the name of CH₃CH(CH₃)CH₂CH₃ be?
1. Identify the longest carbon chain: 4, so the parent compound is butane. 2. Number the carbon to which the alkyl group is attached: 2nd, so it's indicated by the prefix 2-methyl. 3. Put the 2 parts together: 2-methylbutane.
