Bonding electronegativity

Electronegativity (Section 2.1) The ability of an atom to attract electrons in a covalent bond. Electronegativity increases across the periodic table from right to left and from bottom to top. [Pg.1240]

Inductive effect (Sections 2.1, 6.9. 16.4) The electron-attracting or electron-withdrawing effect transmitted through a bonds. Electronegative elements have an electron-withdrawing inductive effect. [Pg.1244]

On the other hand, groups that have a multiple-bonded electronegative atom directly connected to an unsaturated system are —A/ groups. In such cases, we can draw canonical forms in which electrons have been taken from the unsaturated system into the group, for example. [Pg.364]

The bond between the bridgehead carbons of bicyclo[1.1.0]butanes can be either normal or inverted [35]. The normal bond is stabilized by the high s-character (Scheme 16a). In this case, the hybrids on the bridgeheads Y have low s-character for the bridging Y-X bonds. Electronegative atoms X or substituents R at Y stabilize... [Pg.277]

The LIE method has also been used with continuum electrostatic methods. Nicolotti et al. (27) have published a nice report on this use of the LIE method for screening benzamidine inhibitors of thrombin. Another recent study used the atom-bond electronegativity equalization method on force field with the generalized Born (GB) continuum electrostatics approach to predict binding free energies of HIV-1 protease inhibitors (28).
