Which prefix denotes five carbon atoms?

Explanation:
In naming organic compounds, prefixes tell you how many carbon atoms are in the main chain. Two carbons use eth-, three use prop-, four use but-, and five use pent-. A five-carbon example is pentane, C5H12, which shows the five-carbon chain clearly. So pent- is the prefix that denotes five carbon atoms.
