Question

1. Why is hydrogen sulfide more soluble than carbon dioxide in the various glymes used in the Selexol process?

Answer 1

Solution:

hydrogen sulfide more soluble than carbon dioxide in the various glymes used in the Selexol process as hydrogen is directly bound to a strongly electronegative element, oxygen, or nitrogen, or sulfur. And because the more electronegative element polarizes electron-density towards itself, molecular dipoles result, i.e. of the form δ+H−Oδ−−Hδ+δ+H−Oδ−−Hδ+, and these ACT INTERMOLECULARLY. And thus water, a molecule of TRIFLING molecular mass, has a ridiculously high normal boiling point, on the strength of hydrogen-bonding and hence increase its solubility.
