Dear shankerabhi@yahoo.co.in
Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
The carbon-chlorine bond in chlorobenzene is stronger than expected. There is an interaction between one of the lone pairs on the chlorine atom and the delocalised ring electrons, and this strengthens the bond. Hence there is an extra strength of the carbon-halogen bond in aryl halides.
Both Sn1 and SN2 mechanisms involve breaking the carbon-halogen bond at some stage. It is difficult to break this bond. Hence, nucleophillic reactions are difficult in aryl halides. This is not the case in alkyl halides.Regards
