Q16 / 90 · JEE Main 2023 (13 Apr Shift 2) · Chemistry

Given below are two statements :

Statement I : Tropolone is an aromatic compound and has 8π electrons.

Statement II : π electrons of >C=O group in tropolone is involved in aromaticity. In the light of the above statements choose the correct answer from the options given below:

  • Correct answer
    A
    Statement I is true but Statement II is false
  • B
    Statement I is false but Statement II is true
  • C
    Both Statement I and Statement II are false
  • D
    Both Statement I and Statement II are true

Solution

Figure

Tropolone is an aromatic compound and has 8πelectrons (6πe-are endocyclic and 2πe- are exocyclic) and π electrons of >C=O group in tropolone is not involved in aromaticity.

Figure

Hence, the correct answer is option: 'A'.
