from Through the Looking-Glass and What Alice Found There, 1872 Lewis Carrol * * * * * * Derrida, in deconstructionism, posited that readers of a text constructed their own meaning for the text and, with the writer of the text, created a unique reality around that meaning. This theory ...
Lewis acid catalysis significantly enhances the thermally induced degradation of polyperfluorinated ether lubricants. We have used CF3CF2OCF2CF3 and AlF3 as models to investigate via ab initio theory, the Lewis acid-base interactions between polyperfluorinated ethers and Lewis acid sites. The results...

Structure elucidationSynthesis designElectron﹚ithdrawing substituents R in complexes [L n M(PR 2 )] influence the P㎝ bond length due to a decreased σヾonation and enhanced π‐back‐bonding, leading to an increased Lewis acidity of the metal ion and therefore strengthening the M㎜ bond to...
Draw the Lewis structure for CF{eq}_2 {/eq}H{eq}_2 {/eq}. Lewis Structure of a Molecule: The Lewis structure of a molecule shows all the bonds and unshared pairs of electrons present in constituent atoms. A Lewis structure is drawn using all the valence electrons of constituent atoms...
