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 Nucleophilic substitution reactions are categorised into
SN1 and SN2 on the basis of their kinetic properties
