An s-orbital is basically a pretty perfect sphere around the nucleus. A sphere transforms upon itself no matter which element of symmetry you use. Thus, it cannot be the basis of any kind of chirality or other asymmetry. thyroid knot in throat

網頁Stereochemistry is an important issue in any synthesis. This chapter illustrates two key points. First, disconnection should be done at a C C bond where one of the carbon atoms … 網頁1988年12月15日 · The Stereochemical activity or non-activity of the ‘Inert’ pair of electrons on lead (II) in relation to its complex stability and structural properties. Some … 網頁2024年6月19日 · The lone pair is stereochemically active, i.e. it will rotate about. The dipole moments of the axial fluorides will get cancelled, and so will those of the four equatorial fluorides will also cancel each other. Thus, overall, the molecule should be nonpolar. But what effect will the stereochemically active lone pair have on the polarity? thyroid labs do you have to fast
