In cyclopentadienyl anion, each carbon is$\mathrm{s}{\mathrm{p}}^2$-hybridized. The p-orbital or carbon carrying –ve charge has two electrons in the p-orbital. There is one electron in p-orbital of each of the other carbons. Overlapping of the p-orbitals occurs to form$\mathrm{\pi }$-bonds.$\mathrm{\pi }$-clouds above and below the plane of ring has a total of six electrons. Hence, it has aromatic nature in accordance with Huckel (4n + 2)$\mathrm{\pi }$rule corresponding to n = 1.
