Match List I with List II: List I List II (A) Biphenyl (I) Non-benzenoid aromatic (B) Tropylium cation (II) Benzenoid aromatic (C) Cyclooctatetraene (III) Anti-aromatic (D) Cyclopropenyl anion (IV) Non-aromatic Choose the correct answer from the options given below:

Options

  1. A(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
  2. B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
  3. C(A)-(I), (B)-(II), (C)-(IV), (D)-(III)
  4. D(A)-(II), (B)-(III), (C)-(IV), (D)-(I)

Correct answer

B. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Step-by-step solution

(A) Biphenyl consists of two connected benzene rings, making it a benzenoid aromatic compound. So, (A) matches with (II). (B) Tropylium cation is a planar seven-membered ring with 6 electrons. It satisfies Huckel's rule but lacks a benzene ring, making it a non-benzenoid aromatic compound. So, (B) matches with (I). (C) Cyclooctatetraene has 8 electrons ( 4n system). To avoid anti-aromaticity and relieve angle strain, it adopts a non-planar tub shape, making it non-aromatic. So, (C) matches with (IV). (D) Cycloprope
