Question

explain with the help of electronics effect" generally haloalkenes undergo nucleophilic substitution reactions where as haloarenes undergo electrophilic substitution reactions

Answer 1

Haloalkanes have a highly polar halogen carbon bond which provides for easy nucleophilic attack on the carbon, on the other hand in halorenes C-X bond is comparatively stronger and so they only show electrophileic substiton becuse of high charge on benzene ring.
