Which of the following statements are correct with respect to benzene? (i) It forms triozonide with O ₃ . (ii) It is non-planar. (iii) It forms only one monosubstituted product with CH ₃ COCl in the presence of anhyd. AlCl ₃ . (iv) If forms hexachlorobenzene on heating with Cl ₂ under photochemical condition.
Options
- A(i), (ii)
- B(ii), (iii)
- C(i), (iii)
- D(iii), (iv)
Correct answer
C. (i), (iii)
Step-by-step solution
(ii) Benzene is a planar molecule. (iii) Benzene when treated with a mixture of ethanoyl chloride CH ₃ COCl and aluminium chloride as catalyst. A ketone called phenyle thanone (monosubstituted) is obtained. (iv) Benzene when heated with Cl ₂ under photochemical condition gives 1,2,3,4,5,6 -hexachlorocyclohexane.
