Here's how to figure that out:

* Count the carbons: There are three carbon atoms in the chain.

* Identify the type of hydrocarbon: This molecule only contains carbon and hydrogen, making it a hydrocarbon.

* Use the prefix for the number of carbons: The prefix for three carbons is "prop-".

* Add the suffix for a single bond: All the bonds in this molecule are single bonds, so the suffix is "-ane".

Putting it all together, we get propane.
