WebThe 'useBondTypes' option in the rdkit.Chem.rdMolDescriptors.GetMorganFingerprint () function call allows you to control whether or not bond types (bond orders) are considered, when updating identifiers with neighboring atom nodes. The default value is useBondTypes=True. 1. For example, molecule "C=C" has a double bond. WebApr 8, 2016 · A regular covalent bond is formed when two atoms combine orbitals with only one electron each. This gives a molecular orbital with two electrons. However, if the electronegativity differences are large enough, a ionic bond is formed where the most electronegative atom attracts both electrons.
