Important Points

•  Chlorobenzene is a monohalide of benzene that can be prepared by chlorination of benzene in presence of fecl3 as a catalyst. Its chemical formula is C6H5Cl.

C6H6  + Cl2  → C6H5Cl + HCl

• Bromobenzene, C6H5Br, can also be prepared in a similar way.
• Chloro benzene when treated with oxidizing agents, yields chlorobenzene acid, as the side chain goes oxidation.
