A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each atom to attain the equivalent … WebAug 26, 2014 · Ammonia (mp –78, bp –33°C) is hydrogen-bonded in the liquid and solid states. Hydrogen bonding is responsible for ammonia 's remarkably high solubility in water. Many organic (carboxylic) acids form hydrogen-bonded dimers in the solid state.
