Inorganic Anion - an overview ScienceDirect Topics

WebHydrogen bonds (HBs) play a crucial role in the physicochemical properties of ionic liquids (ILs). To date, HBs between cations and anions (Ca–An) or between cations (Ca–Ca) in ILs have been reported extensively. Here, we provided DFT evidence for the existence of HBs between anions (An–An) in the IL 1-(2-hy WebResonance effects can stabilize the anion. This is especially true when the anion is stabilized as a result of aromaticity. Geometry also affects the orbital hybridization of the charge-bearing carbanion. The greater the s-character of the charge-bearing atom, the more stable the anion. ninet motorcycle
