Options
- A(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
- B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
- C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
- D(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
Correct answer
C. (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
Step-by-step solution
(A) Benzene reacts with chlorine in the presence of UV light to undergo free radical addition, forming benzene hexachloride ( C ₆ H ₆ Cl ₆ ). So, (A) matches with (II). (B) Benzene reacts with excess chlorine in the presence of anhydrous AlCl ₃ (a Lewis acid) in the dark to undergo electrophilic substitution, forming hexachlorobenzene ( C ₆ Cl ₆ ). So, (B) matches with (I). (C) Benzene undergoes catalytic hydrogenation with 3 H ₂ in the presence of finely divided nickel at high temperature and pressure to form cycl
