Which of the following statements are correct?

Options

A. The C-Cl bond in chlorobenzene is shorter than in chloromethane.
B. The C-Cl bond in chlorobenzene has some double bond character.
C. It is difficult to replace chlorine from chlorobenzene than from bernzyl chloride.
D. Chlorobenzene on further chlorination gives m-dichlorobenene.

Explanation

To determine which statements are correct regarding the properties of alkyl and aryl halides, let's analyze each statement step by step.

### Step 1: Analyzing the First Statement
**Statement:** The C-Cl bond in chlorobenzene is stronger than in chloromethane.

- **Explanation:** In chlorobenzene (C6H5Cl), the chlorine atom is bonded to a carbon in a benzene ring. The presence of the aromatic system allows for resonance stabilization, which means that the C-Cl bond is somewhat strengthened due to the delocalization of electrons. In chloromethane (CH3Cl), the C-Cl bond does not benefit from such resonance, making it weaker. Therefore, this statement is **correct**.
