Benzene when reacted with chlorine in ultraviolet rays produces:
Correct answer: A. Hexachlorocyclohexane
- A. Hexachlorocyclohexane
- B. p-Dichlorobenzene
- C. Benzotrichloride
- D. Benzalchloride
Explanation
The reaction of benzene with chlorine in the presence of ultraviolet light is a free radical halogenation reaction. The UV light provides the energy needed to break the chlorine molecule into chlorine radicals. These radicals then attack the benzene ring, leading to the formation of a series of chlorinated products.The primary product of this reaction is hexachlorocyclohexane (HCH), also known as lindane. HCH is a cyclic compound with six chlorine atoms attached to the cyclohexane ring.
