Here symbols in parentheses represent unshared electrons attached to C and O, respectively, and those in braces represent shared electrons. An excited carbon atom 6S lies about 1.6 v. e. above the normal state, but can still form only a double bond with oxygen, so that the resultant molecule should be excited. We write... 

The formation of Q might then proceed as follows. A low energy electron attaches to the P ground state of the oxygen atom to form 0 (2p P ). 

The converse of this effect may be achieved when we introduce an electron-donor group and this may be achieved through silyl derivatives. A silyl group attached to oxygen [4] will enhance nucleophilicity of the nearby... 

Attachment to oxygen increases the electron-withdrawing nature of the sulfur, deshielding the hydrogens in the sulfoxide more than in the sulfide ... 

Figure 1.20. Representations of water (H2O). (a) A representation of the occupied nonbonding orbitals and (b) a representation indicating that in addition to the two hydrogens attached to oxygen, there are also two pairs of nonbonded electrons. The representations were created using the MOViewer in WebMO version 6.0.002p.

The oxygen atom transfer reaction described above has been shown as a two-electron inner sphere transfer. Oxidation of primary and secondary alcohols by MnO and by HCr04 have been rationalized as two-electron transfers that require removal of a proton from the carbon attached to oxygen. Manganese(V) has been detected as an intermediate product, and chromate ester precursors to reactions suggest the following activated states ...
