Why can aryl halides not be prepared by ...

Why can aryl halides not be prepared by reaction of phenol with HCl in the presence of `ZnCl_(2)`?

Text Solution

Verified by Experts

Due to resonance in phenol, C-O bond of phenol has some partial double bond character. Partial double bond character strengthen the 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
So alkyl halides can be prepared by the reaction of alcohols with HCI in the presence of `ZnCl_(2)` while aryl halides can not be prepared by reaction of phenol with HCl in the presence of `ZnCl_(2)`.
`underset("Phenol")(C_(6)H_(5)OH)underset(ZnCl_(2))overset(HCl)to`NO reaction
`underset("Alcohol")(RCH_(2)OH)underset(ZnCl_(2))overset(HCl)tounderset("Alkyl chloride")(RCH_(2)Cl)+H_(2)O`
