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

Options

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

Answer

To solve the question, we need to analyze the two statements regarding tropolone and determine their validity.

### Step-by-Step Solution:

1. **Understanding Tropolone Structure**:
- Tropolone is a bicyclic compound with a hydroxyl group (-OH) and a carbonyl group (C=O) in its structure.
- The structure can be represented as follows:
```
O
||
C1-C2
| |
C3--C4
\ /
C5
|
OH
```

2. **Determining Aromaticity**:
- For a compound to be aromatic, it must satisfy Huckel's rule, which states that a compound must have \(4n + 2\) π electrons, where \(n\) is a non-negative integer.
- In the case of tropolone, we need to count the π electrons:
- The double bond between C1 and C2 contributes 2 π electrons.
- The double bond between C3 and C4 contributes another 2 π electrons.
- The C=O group contributes 2 π electrons from the carbonyl oxygen.
- The hydroxyl group does not contribute additional π electrons to the aromatic system.
- Therefore, the total number of π electrons in tropolone is \(2 (C=C) + 2 (C=C) + 2 (C=O) = 6 + 2 = 8\) π electrons.

3. **Evaluating Statement I**:
- Statement I claims that tropolone is an aromatic compound and has 8 π electrons.
- Since we have confirmed that tropolone has 8 π electrons and is indeed aromatic (it follows Huckel's rule with 8 π electrons), **Statement I is true**.

4. **Evaluating Statement II**:
- Statement II claims that the π electrons of the C=O group in tropolone are involved in aromaticity.
- While the C=O group does contribute to the overall electron count, its electrons do not participate in the aromatic π system.
- The aromaticity is primarily due to the 6 π electrons from the cyclic structure. The C=O group participates in resonance but does not contribute to the aromatic character.
- Therefore, **Statement II is false**.

5. **Conclusion**:
- Based on the evaluations, we conclude that:
- Statement I is true.
- Statement II is false.
- Thus, the correct answer is option 2.
