The most stable form of glucose is the chair conformation. In the chair conformation, the glucose molecule adopts a stable, three-dimensional form that minimizes steric clashes between atoms. This form is the most energetically favorable and commonly found in nature, particularly in polysaccharides like starch and cellulose.
The compounds \( [\text{PtCl}_2(\text{NH}_3)_4]\text{Br}_2 \) and \( [\text{PtBr}_2(\text{NH}_3)_4]\text{Cl}_2 \) constitute a pair of:
