Bonding charge concentration

In each of these hydrocarbons we also see a C—H bonding charge concentration with a maximum in the carbon valence shell corresponding to the C—H bonding domain, and...

Fig. 7.6. Relief maps of — V p for the equatorial (upper) and axial (lower) planes of CIF3. The chlorine atom exhibits three shells of charge concentration. The equatorial plane shows the presence of two non-bonded and one smaller bonded charge concentration. In the axial plane there are three bonded charge concentrations and a fourth apparent maximum which is actually another view of the (3, — 1) critical point between the two non-bonded maxima. Thus the VSCC of Cl possesses two non-bonded and three bonded concentrations of charge.

Critical points in the VSCCs of the respective base and acid atoms. This information enables one to predict positions of attack within a molecule and, hence, the geometries of approach of the reactan For example, a keto oxygen in the formamide molecule has two large non-bonded charge concentrations in the plane of the nuclei (VV = 6.25 and — 6.30 au), while the...
