The generally observed decrease of the electrostatic energy in the complex with increasing solvent polarity has led to the assumption that the stability of the complexes with ion‐pair hydrogen bonds decreases with increasing solvent polarity. Besides, the smaller solvent‐accessible surface ...
An electronegativity difference of 1.70 is considered 50 percent covalent and 50 percent ionic. As the difference in electronegativity increases, the bond becomes more ionic in character. Generally, ionic bonds form when the electro- negativity difference is greater than 1.70. However, this cutoff is...
The compound must at least contain one or more polar bonds. A polar bond is formed when an electronegative atom is bonded to a less electronegative atom. The dipole moment of the polar bonds must not cancel out. Thus, the shape of the mole...
