Chlorobenzene overview
The stored Lewis connectivity is C₆H₅—Cl. Chlorine replaces one benzene hydrogen and retains three lone pairs; the ring remains aromatic.
How to draw C₆H₅Cl
Count 36 valence electrons. Include charge adjustments before drawing.
Use the reviewed connectivity C₆H₅—Cl. Do not infer a different isomer from the formula alone.
Place the required single, double or multiple bonds. Keep a running electron total.
Complete terminal valence shells and add lone pairs or formal charges. Chlorine replaces one benzene hydrogen and retains three lone pairs; the ring remains aromatic.
Verify the total electron count and geometry. The reviewed geometry is Planar aromatic ring.
Why this example matters
Chlorine replaces one benzene hydrogen and retains three lone pairs; the ring remains aromatic.
Scope and model limits
The Lewis display uses a representative aromatic contributor. It does not mean the ring bonds are permanently alternating.
Common mistakes
Drawing cyclohexyl chloride
Omitting chlorine lone pairs
Adding a full C=Cl double bond as the only structure
