प्रश्न
Explain why nucleophilic substitution reactions are not very common in phenols.
Advertisements
उत्तर
The C – O bond in phenols has some double-bond character due to resonance and hence cannot be easily cleaved by nucleophiles. So, nucleophilic substitution reactions are not very common in phenols and they give many electrophilic substitution reactions.
