Question

Assertion (A): The compound cyclooctane has the following structural formula:

It is cyclic and has conjugated 8π-electron system but it is not an aromatic compound.

Reason (R): (4n + 2)π electrons rule does not hold good and ring is not planar.

Options

  • Both A and R are correct and R is the correct explanation of A.

  • Both A and R are correct but R is not the correct explanation of A.

  • Both A and R are not correct.

  • A is not correct but R is correct.

MCQ
