Hybridization. Accounting. For molecules with more than two atoms, it is more difficult to distinguish between the polar and non-polar molecules, because two or more polar bonds may cancel each other. Note that each sp orbital contains one lobe that is significantly larger than the other. For molecules with lone pairs, the bonding orbitals are isovalent hybrids since different fractions of s and p orbitals are mixed to achieve optimal bonding. The SF 4 hybridization structure looks as given below. This is because hybrids ligands, which finely integrate two pharmacophoric functionalities, are inherently more adequate to face the complex and multifactorial nature of such maladies. This molecule is tetrahedral in structure as well as in shape, since there are no lone pairs and the number of σ-bonds is equal to the steric number. sp3 hybridization: sum of attached atoms + lone pairs = 4 sp2 hybridization: sum of attached atoms + lone pairs = 3 sp hybridization: sum of attached atoms + lone pairs = 2 Where it can start to get slightly tricky is in dealing with line diagrams containing implicit (“hidden”) hydrogens and lone pairs. 2. molecular hybridization .
