Editing Stereoisomerism (section)

==Le Bel-van't Hoff rule==
[[Le Bel-van't Hoff rule]] states that for a structure with ''n'' [[asymmetric carbon]] atoms, there is a maximum of 2<sup>''n''</sup> different stereoisomers possible. As an example, <small>D</small>-glucose is an [[aldohexose]] and has the formula C<sub>6</sub>H<sub>12</sub>O<sub>6</sub>. Four of its six carbon atoms are stereogenic, which means <small>D</small>-glucose is one of 2<sup>4</sup>=16 possible stereoisomers.<ref>{{cite journal | pmc=6396334 | year=2019 | last1=Blackmond | first1=D.
