Why can aryl halides not be prepared by reaction of phenol with HCL in
the presence of ZnCl,?
character which strengthen the C-OH bond. So, It is difficult to break this C—O bond of phenol while the C—O bond of alcohol is purely single bond and
comparatively weaker bond because here delocalization is not possible. So alkyl halides will be obtained by the tratment of aicohols with HCI in the presence of
ZnCl as lewis acid catalyat while aryl halides will not be obtained by reaction of phenol with HCl in the presence of ZnCl.
