IPA: //ˈhæloʊˌkɑːrbən//
KK: /ˈhæl.oʊˌkɑːr.bən/
A type of chemical compound made of carbon and one or more halogen elements, often used in refrigeration and as solvents.
Halocarbons are commonly used in air conditioning systems.
Halocarbon is formed from "halo-" (from Greek "halos", meaning salt) and "carbon" (from Latin "carbo", meaning coal or carbon). The term refers to organic compounds that contain carbon and halogens, which are elements derived from salts.
Think of 'halo-' meaning salt and 'carbon' referring to coal — halocarbon compounds are those that contain carbon and elements derived from salts.
