Options
- A(A)-(IV), (B)-(II), (C)-(III), (D)-(I)
- B(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
- C(A)-(I), (B)-(III), (C)-(II), (D)-(IV)
- D(A)-(III), (B)-(II), (C)-(I), (D)-(IV)
Correct answer
B. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
Step-by-step solution
(A) The mixture of o -nitrotoluene and p -nitrotoluene contains isomers with a small difference in boiling points and no hydrogen bonding. They are separated by fractional distillation. (B) The mixture of o -dichlorobenzene and p -dichlorobenzene is separated by fractional crystallization because the para-isomer has a much higher melting point due to its symmetrical structure. (C) Chloroform (bp ~334 K) and aniline (bp ~457 K) have a large difference in their boiling points and are separated by simple distillation.
