Why can aryl halides not be prepared by reaction of phenol with HCl in the presence of ZnCl_(2)? |
Answer» SOLUTION :Due to resonance, C-O bond in phenols has some double bond character but in alcohols, it is a pure SINGLE bond. In other words, C-O bond in phenols is stronger than C-O bond in alcohols and hence difficult to bereak. As a result, phenols do not react WITHHCL in presence of anhydrous `ZnCl_(2)` to form the corresponding ARYL chlorides but alcohols react to form the corresponding ALKYL chlorides.
