Why can aryl halides not be prepared by reaction of phenol with \[\ce{HCl}\] in the presence of \[\ce{ZnCl2}\]?

उत्तर
Aryl halides can't be prepared by reaction of phenol with \[\ce{HCl}\] in presence of \[\ce{ZnCl2}\] because the carbon-oxygen bond in phenols has partial double bond character and it, being stronger than a single bond, is difficult to break.
