Which of the following compounds are antiaromatic

Options

  1. A(I) and (V)
  2. B(II) and (V)
  3. C(I) and (IV)
  4. D(V) and (VI)

Correct answer

D. (V) and (VI)

Step-by-step solution

For a compound to be aromatic it must have (4 n+2) e⁻ and system should be planar where n is an integer. (V) and (VI) both have 4 e⁻ and planar structure. Hence are Antiaromatic
