In this section, the life test results for ceramic bearings will be presented. Specifically, life test results for three types of bearings will be discussed all-ceramic bearings, hybrid ceramic bearings, and steel bearings. 

All the examples of reactivity in acidic medium (Scheme 40) involve a reagent with a sp C hybridized electrophilic center, but the actual reactive species generated bears a sp C electrophilic center. In this case, exocyclic N-alkylation is not surprising (see Section III.2). 

Thus the reactivity of 2-aminothiazole derivatives toward reactants bearing a sp C hybridized electrophilic center follows the general pattern ... 

The carbon that bears the functional group is sp hybridized m alcohols and alkyl halides Figure 4 1 illustrates bonding m methanol The bond angles at carbon are approximately tetrahedral as is the C—O—H angle A similar orbital hybridization model applies to alkyl halides with the halogen connected to sp hybridized carbon by a ct bond Carbon-halogen bond distances m alkyl halides increase m the order C—F (140 pm) < C—Cl (179 pm) < C—Br (197 pm) < C—I (216 pm)... 

It must be emphasized that we are not dealing with an equilibrium between two isomeric carbocations There is only one carbocation Its structure is not adequately represented by either of the individual resonance forms but is a hybrid having qualities of both of them The carbocation has more of the character of A than B because resonance struc ture A IS more stable than B Water attacks faster at the tertiary carbon because it bears a greater share of the positive charge... 

The three carbons of allene he in a straight line with relatively short carbon-carbon bond distances of 131 pm The central carbon because it bears only two substituents is sp hybridized The terminal carbons of allene are sp hybridized...

Complexes of d- and /-block metals can be described in terms of hybridization schemes, each associated with a particular shape. Bearing in mind that the number of atomic orbitals hybridized must be the same as the number of hybrid orbitals produced, match the hybrid orbitals sp1d, sp fd , and sp d3f to the following shapes (a) pentagonal bipyramidal ... 

Some 50 years have now passed since the publication of a series of papers bearing the title The Nature of the Chemical Bond. 1 7 These papers have provided chemists, physicists, biologists, and mineralogists with the conceptual framework, based on simple valence bond theory and the theory of hybrid bond orbitals, required to investigate a myriad of problems involving the nature of the bonding exhibited in molecules and solids. The ideas contained in these papers were subsequently elaborated on in The Nature of the Chemical Bond which is probably the most often-cited book in the scientific literature.9...
