Straight-chain hydrocarbon molecules that contain only singly-bonded carbons are called alkanes.

When naming these molecules, the final syllable in their name is "ane."

1. Find and name the longest continuous carbon chain.
2. Identify and name groups attached to this chain.
3. Number the chain consecutively, starting at the end nearest a substituent group.
4. Designate the location of each substituent group by an appropriate number and name.
