Identify the products $(P),(Q)$ and $(R)$ formed from the following reactions.

• Correct answer
  A

  $(P)$ : Benzene hexachloride $(Q)$ : Hexachlorobenzene $(R)$: Cyclohexanol
• B

  $(P)$ : Hexachlorobenzene $(Q)$ : Benzene hexachloride $(R)$ : Cyclohexenol
• C

  $(P)$ : Benzene hexachloride $(Q)$ : Hexachlorobenzene $(R)$ : Cyclohexane
• D

  $(P)$ : Hexachlorobenzene $(Q)$ : Benzene hexachloride $(R)$ : Cyclohexane

Solution

The ring delocalisation is permanently broken and a chlorine atom adds on to each carbon atom and forms benzene hexachloride.


So, $(P)=$ Benzene hexachloride $(Q)=$ Hexachlorobenzene $(R)=$ Cyclohexanol.

Hence, the correct answer is option: 'A'.
