Aromaticity - Coursework Example N2 configuration , sp3 hybridization. All atoms within the cycle are sp2 hybridized, number of pi-electrons is 10 (4n+2, n=2), so the cycle is aromatic, the whole molecule is not as it is not cyclic. S configuration , sp2 hybridization, electrons in the lone pair are pi-electrons. All atoms are sp2 hybridized, molecule is planar and conjugated, number of pi-electrons is 10 (4n+2, n=2), so it is aromatic. N5 configuration , sp3 hybridization. All atoms within the cycle are sp2 hybridized, number of pi-electrons is 10 (4n+2, n=2), so the cycle is aromatic, while the whole molecule is not as it is not planar. 10) O configuration , sp2 hybridization, electrons in the lone pair are pi-electrons. All atoms are sp2 hybridized, molecule is planar, number of pi-electrons is 8 (4n+2, n=1.5), so it is not aromatic. O possible configurations a) , b). Configuration a), Sp2 hybridized, with one pi-electron. All atoms are sp2 hybridized, molecule is planar and conjugated, number of pi-electrons is 6 (4n+2, n=1), so it is
