Which of the following prefixes indicates the presence of fluorine in a compound?

• A. Bromo-
• B. Chloro-
• C. Fluoro-
• D. Iodo-

Answer: (C)

The prefix "Fluoro-" specifically indicates the presence of fluorine in a compound. In organic chemistry, various prefixes are used to denote different halogen substituents. The term "Fluoro-" directly refers to the fluorine atom that is attached to the parent hydrocarbon structure. For example, in a compound named "fluorobenzene," the "fluoro-" prefix signifies that a fluorine atom is substituted on a benzene ring. This distinguishes it from other halogens such as bromine, chlorine, and iodine, which have their respective prefixes: "bromo-," "chloro-," and "iodo-." Understanding these prefixes is essential for identifying and naming organic compounds accurately, especially when discussing the functional groups or substituents present in molecular structures.
