IB DP Chemistry: SL复习笔记10.1.5 Organic Families - Halogenoalkanes

• Halogenoalkanes or Haloalkanes have the general molecular formula, C_nH_2n+1X, where X represents a halogen
• Haloalkanes are named using the prefix chloro-, bromo- or iodo-, with the ending -ane
• In molecules with a straight chain of three or more carbon atoms, the position of the halogen atom must also be specified
• The carbon atoms on the straight chain must be numbered, starting with the end closest to the halogen atom
• The number of the carbon atom attached to the halogen is indicated before the prefix:

• The position of all halogens in dihaloalkanes except those with one carbon atom must be specified.
• If there is more than one of the same type of halogen atom on the molecule, the di (two), tri (three) or tetra (four) prefixes must also be used
