The correct Answer is:
To determine which of the given compounds is aromatic, we will apply Huckel's rule and check the necessary conditions for aromaticity. ### Step-by-Step Solution: 1. **Identify the Compounds**: First, we need to clearly identify the compounds listed in options A, B, C, and D. For the sake of this solution, let's assume they are labeled as follows: - Option A: Compound 1 - Option B: Compound 2 - Option C: Compound 3 - Option D: Compound 4 2. **Check for Cyclic Structure**: For a compound to be aromatic, it must be cyclic. We will examine each compound to see if it has a ring structure. 3. **Hybridization of Atoms**: All atoms in the cyclic structure must be sp² hybridized. We will analyze the hybridization of the atoms in each compound. 4. **Planarity**: The compound must be planar, which is typically satisfied if all the involved atoms are sp² hybridized. 5. **Count the Pi Electrons**: We will count the number of pi electrons in the cyclic structure. Each double bond contributes 2 pi electrons. 6. **Apply Huckel's Rule**: According to Huckel's rule, a compound is aromatic if it has a cyclic cloud of pi electrons that follows the formula \(4n + 2\) where \(n\) is a non-negative integer (0, 1, 2, ...). We will check if the number of pi electrons in each compound fits this formula. 7. **Determine Aromaticity**: - If a compound has \(4n + 2\) pi electrons, it is aromatic. - If it has \(4n\) pi electrons, it is anti-aromatic. - If it does not meet these criteria, it is non-aromatic. 8. **Conclusion**: After analyzing all the compounds, we will conclude which one is aromatic based on the above criteria. ### Example Analysis: - **Option A**: Assume it has 6 pi electrons (which is \(4(1) + 2\)). This compound is aromatic. - **Option B**: Assume it has 4 pi electrons (which is \(4(1)\)). This compound is anti-aromatic. - **Option C**: Assume it has 2 pi electrons (which is \(4(0) + 2\)). This compound is aromatic. - **Option D**: Assume it has 8 pi electrons (which is \(4(2)\)). This compound is anti-aromatic. ### Final Answer: Based on the analysis, if Option A has 6 pi electrons and Option C has 2 pi electrons, both A and C are aromatic. However, if the question asks for only one aromatic compound, we would select the one that is most commonly recognized as aromatic, which is typically the one with 6 pi electrons.

To determine which of the given compounds is aromatic, we will apply Huckel's rule and check the necessary conditions for aromaticity. ### Step-by-Step Solution: 1. **Identify the Compounds**: First, we need to clearly identify the compounds listed in options A, B, C, and D. For the sake of this solution, let's assume they are labeled as follows: - Option A: Compound 1 - Option B: Compound 2 - Option C: Compound 3 ...
