Cyclobutene and Aromaticity
Introduction:
Cyclobutene is a cyclic hydrocarbon with four carbon atoms and two double bonds. Aromaticity refers to a property exhibited by some cyclic compounds that have a specific arrangement of pi-electrons, resulting in enhanced stability. In this question, we are given that when cyclobutene is refluxed in the presence of potassium metal, an aromatic system is formed. We need to determine the number of pi-electrons involved in this aromatic system.
Aromaticity and Pi-Electrons:
Aromatic compounds possess a cyclic structure, a conjugated system of pi-electrons, and meet certain criteria known as Hückel's rule. According to Hückel's rule, a compound is considered aromatic if it fulfills the following criteria:
1. The compound must have a cyclic structure.
2. The compound must possess a fully conjugated system of pi-electrons.
3. The compound must have a planar structure.
4. The compound must have 4n + 2 pi-electrons, where n is an integer (n = 0, 1, 2, ...).
Analysis:
Cyclobutene has a cyclic structure and two double bonds, which contribute pi-electrons to the system. To determine whether the resulting system is aromatic, we need to calculate the number of pi-electrons.
Calculating the Number of Pi-Electrons:
1. Cyclobutene contains two double bonds, and each double bond contributes two pi-electrons. Therefore, the total number of pi-electrons from the double bonds is 2 x 2 = 4.
Conclusion:
Therefore, the aromatic system formed from the reflux of cyclobutene in the presence of potassium metal involves a total of 4 pi-electrons.
