Fluorides and iodides are best prepared by halogen
exchange method The boiling points of organohalogen compounds are comparatively higher than the
corresponding hydrocarbons because of strong dipole-dipole and van der Waals forces
of attraction These are slightly soluble in water but completely soluble in organic
solvents The polarity of carbon-halogen bond of alkyl halides is responsible for their
nucleophilic substitution, elimination and their reaction with metal atoms to form
organometallic compounds
