How are halogenated hydrocarbons named?

• A. By naming the hydrocarbon and adding an "o" to the end.
• B. By naming the alkane and adding the halogen as a prefix.
• C. By naming the halogen group first followed by the alkane name.
• D. By using both the alkyl and halo- precedents in the name.

Answer: (B)

Halogenated hydrocarbons are named by identifying the longest carbon chain of the parent hydrocarbon and then adding the halogen as a prefix. This approach maintains the systematic naming conventions of organic chemistry. In this method, the alkane root name is determined first, which corresponds to the number of carbon atoms in the longest continuous chain. Subsequently, the halogen substituents are named as prefixes such as "fluoro-" for fluorine, "chloro-" for chlorine, "bromo-" for bromine, and "iodo-" for iodine. Each halogen prefix is listed in alphabetical order, ensuring clarity in the name. This systematic approach allows for precise identification of the compound, providing important information about its structure. Understanding this naming convention is essential for successful communication about chemical substances in organic chemistry.
