Question

Given below are two statements:
Statement I: Tropolone is an aromatic compound and has 8л electrons. 
Statement II: 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

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

Answer 1

The Correct Option is C

1. Statement I: Tropolone is an aromatic compound with a conjugated ring system containing 8 \(\pi\) electrons: - 6 \(\pi\) electrons are endocyclic (within the ring). - 2 \(\pi\) electrons from the \(>\text{C}=\text{O}\) group are exocyclic (outside the ring). Hence, tropolone satisfies the conditions of aromaticity. Therefore, Statement I is correct. 

2. Statement II: The \(\pi\) electrons of the \(>\text{C}=\text{O}\) group are not involved in the aromaticity of the compound, as they are exocyclic and do not contribute to the conjugated system of the ring. Therefore, Statement II is incorrect. ### Diagram: \[ \text{Tropolone: Aromatic compound with 6 \(\pi\) endocyclic electrons} \] \[ \text{Structure:} \] \[ \text{OH} \quad \text{C}=\text{O} \]

Conclusion: Statement I is true, but Statement II is false.
