What prefix is used to indicate the presence of alkyl halide in a compound with chlorine?

The prefix used to indicate the presence of an alkyl halide in a compound with chlorine is "Chloro-." In organic chemistry, halogens are often denoted using specific prefixes that correspond to the halogen present in the compound.

The prefix "Chloro-" specifically indicates that chlorine is part of the molecular structure. For instance, in a compound like chlorobutane, the "Chloro-" prefix signifies that one or more hydrogen atoms in butane have been replaced by chlorine atoms.

Each of the alternative prefixes corresponds to different halogens: "Bromo-" for bromine, "Fluoro-" for fluorine, and "Iodo-" for iodine. Since the question specifically focuses on chlorine as the halogen, "Chloro-" is the appropriate prefix to describe compounds incorporating chlorine.
