Which prefix denotes six carbon atoms?

Explanation:
In organic naming, prefixes tell how many carbon atoms are in the main chain. The six-carbon prefix is hex-. So a six-carbon alkane is hexane, and a six-carbon substituent would be hexyl. Eth denotes two carbons, prop three, and but four. Since the question asks for six carbons, hex is the correct prefix. For example, hexane has six carbon atoms (C6).
