Witryna27 wrz 2024 · A localized lone pair is a lone pair electron that does not participate in resonance. What is localized bonding? Localized chemical bond is that one in which the bonded electrons are confined (limited) to a concentrated region between two separate atoms. It is a two electrons two centred bond and is local to a single pair of atoms.
