Covalent Bonds:Covalent bonds may be polar or nonpolar depending on the electronegativity values of the two atoms involved in the bond. Electronegativity is the atom's ability to withdraw electrons toward itself. When there is a significant electronegativity difference between two atoms, a bond ...

[20] examined this problem by considering WnOm clusters and demonstrated that in materials characterized by strong covalent or ionic bond, very small clusters have properties similar to their bulk. To shed light on how the properties of oxide clusters evolve as a function of the cluster size, ...
Biaryl scaffolds are found in natural products and drug molecules and exhibit a wide range of biological activities. In past decade, the transition metal-catalyzed C–H arylation reaction came out as an effective tool for the construction of biaryl motif
Charge-shift bonds form a distinct class of bonds where all or most of the bond energy is provided by the resonance energy between the covalent and ionic structures of the bond. This phenomenon is not associated with bond polarity, and charge-shift bonds exist among homonuclear (e.g., F2,...
