Explain why nucleophilic substitution reactions rae not very common in phenols.

Explanation

To explain why nucleophilic substitution reactions are not very common in phenols, we can break down the reasoning into several steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Phenols**:
- Phenols are compounds where a hydroxyl group (-OH) is directly attached to an aromatic ring. The aromatic ring consists of sp² hybridized carbon atoms, which are part of a conjugated π-electron system.

2. **Resonance Stabilization**:
