Rdkit formal charge
WebJun 24, 2024 · Standardizing a molecule using RDKit Cheminformatics is hard. That is a great quote from Prof. Paul Finn. I think part of it is due to the nature of chemistry (e.g. which is the correct tautomer for this molecule?), and part of it is because of the lack of “standard” process definitions.

WebAug 10, 2024 · Re: [Rdkit-discuss] Assigning formal charges. Hi Juuso, A quick solution that seems like it would covert most cases would be to construct a molecule from you input without doing sanitization, calculate the atomic valences in non-strict mode, and then to identify all neutral N atoms with a valence of 4 and add a positive charge to them Here's …

WebThe formal charge of an atom in a molecule is the charge that would reside on the atom if all of the bonding electrons were shared equally. We can calculate an atom's formal charge using the equation FC = VE - [LPE - ½ (BE)], where VE = the number of valence electrons on the free atom, LPE = the number of lone pair electrons on the atom in the ...
