The number of shared and unshared pairs of electrons in the given molecule is to be counted and the formal charge on C and Cl atoms is to be assigned. Concept Introduction: Some organic functional groups (even neutral functional groups) have formal charges on individual atoms. To calculate the formal charge on an atom in any given structure it is necessary to distinguish between the electrons that make up an atom’s octet and the electrons that formally “belong” to an atom. In any given Lewis structure all electrons associated with an atom either as an unshared pair or shared pair are part of that atom’s octet.
