lonepairbearing
Lonepairbearing refers to atoms, molecules, or molecular centers that possess one or more nonbonding valence electron pairs, also called lone pairs. These pairs are localized on a specific atom and are not involved in covalent bonding under standard conditions, though they can participate in donor-acceptor interactions in reactive contexts.
Lone pairs influence molecular geometry and reactivity. In valence shell electron pair repulsion (VSEPR) theory, lone
Lone pairs also function as Lewis bases, donating electron density to electron-poor species. This makes lone-pair
Examples of lone-pair bearing sites are found across organic and inorganic chemistry: the oxygen atoms in water
