Nomenclature of Haloalkanes

Haloalkanes (or alkyl halides) have the general formula R-X, where X is F, Cl, Br, or I.

  • Naming a substitute: are named with the prefix fluoro-, chlorine-, bromine-, iodine– followed by the name of the hydrocarbon with the same number of carbons as the radical to which it is attached (recommendation C-102.1).
  • Nomenclature radical-function: are named similarly to salts ( … floride, … chloride, … bromide, etc.) preceded by the name of the radical to which it is attached (recommendation C-103.1).

The polyhalomethanes are compounds very frequently used in the chemical industry, which retain their common or trivial names (recommendation R-103.1): fluoroform (CHF3), chloroform (CHCl3), bromoform (CHBr3), iodoform (CHI3), generally haloform (CHX3). Also, methylene halide (CH2X2), such as methylene chloride (CH2C2), or methylene bromide (CH2Br2).
