The modification of activated carbon fibres prepared from a commercial textile acrylic fibre into materials with monolithic shape using phenolic resin as binder was studied. The molecular sieving properties for the gas separations CO 2/CH 4 and O 2/N 2 were evaluated from the gas uptake volume ...

Molecular Shape While Lewis dot structures can tell us how the atoms in molecules are bonded to each other, they don’t tell us the shape of the molecule. In this section, we’ll discuss the methods for predicting molecular shape. The most important thing to remember when attempting to ...

1,2-Dichloroethane has a linear shape and electron-withdrawing chlorine groups at both ends; thus, it is a good guest molecule for pillar[5]arenes and works as a template solvent to form pillar[5]arenes. The template effect is clarified when chloroform is used as a solvent. A mixture of...

These results are rationalized by a higher degree of p-interactions with C70 due to its ellipsoid shape (see Supplementary Figs 7–10). This is confirmed by DFT calcula- tions, which indicate a more favourable porphyrin–fullerene interaction for C70 fullerene molecule (see Supplementary Fig. 11...
Explain the VSEPR theory in detail and give examples of molecules for each molecular shape. Valence Shell: The shell that lies outermost in an element is the valence shell. The electrons present in the valence shells are valence electrons. The number of valence elect...
