Cycloalkene nomenclature is a systematic approach to naming cyclic hydrocarbons with double bonds, following IUPAC guidelines. It involves identifying the longest carbon chain, assigning the lowest locants to double bonds and substituents, and using descriptors for stereochemistry. This nomenclature is vital in organic chemistry, medicinal chemistry, and agrochemistry for clear communication and compound identification.
