Benzene Chlorine Reaction in Sunlight
The reaction of benzene and chlorine under light
The previous research chemist wants to study the reaction of benzene and chlorine under light. Benzene is a cyclic hydrocarbon with special structure and properties. Chlorine is an active halogen gas.
When benzene encounters chlorine and is placed under light conditions, its reaction begins. Light provides energy, enabling chlorine molecules to be energized and cleaved. Under the action of light, the covalent bond of chlorine molecules ($Cl_2 $) breaks, forming a highly reactive chlorine radical ($Cl · $).
This chlorine radical is highly reactive and interacts with the benzene ring. The electron cloud structure of the benzene ring makes it easy for chlorine radicals to attack. However, the benzene ring is stable, and the reaction is not as direct addition as an olefin. During the
reaction, the chlorine radical first captures the hydrogen atom on the benzene ring to form hydrogen chloride ($HCl $) and benzene radical. The benzene radical immediately interacts with the chlorine molecule to form chlorobenzene ($C_6H_5Cl $) and new chlorine radicals. The new chlorine radical can continue to initiate subsequent reactions.
This reaction process is complicated. In addition to generating monochlorobenzene, it may also generate polychlorobenzene. The proportion of products varies depending on the reaction conditions and the proportion of reactants. If there is too much chlorine gas and sufficient light, more hydrogen atoms on the benzene ring will be replaced by chlorine atoms to form various chlorobenzene products such as dichlorobenzene and trichlorobenzene. The reaction of benzene and chlorine under light is a typical example of chemical change, providing a lot of basis for chemical research and industrial application, enabling scholars to understand its reaction mechanism, and then make good use of it.
