What is the IUPAC name for the alkyl halides?

The IUPAC nomenclature for alkyl halides involves naming the alkyl group first, followed by the halogen substituent. The halogen is named as a prefix based on its position in the Periodic Table (fluoro-, chloro-, bromo-, iodo-). The alkyl group is named based on the number of carbon atoms in the longest continuous chain, with the suffix -ane changed to -yl. For example, chloromethane is the IUPAC name for CH3Cl.
