, Haloalkanes and Haloarenes
INTRODUCTION : -
The derivatives of aliphatic
halogen
and aromatic hydrocarbons are called alkyl
halide ( Halo alkahest and aryl halide ( Halo . aren.es )
Halo alkanes contain
halogen atom attached to
the spshyboidised c- atom
of an alkyl grouts :
whereas Haloarenes
contain halogen atom attached to spa hybridised
c- atom of an
aryl grouts .
CLASSIFICATION OF HALO ALKANES & HALO ARENE
(A) On the basis of no .
(A) On the basis of
hybridisation state
of halogen atoms
