Abstract:
Ring-stacked boranes of the B(10)H(10)(2)(-) and B(12)H(12)(2)(-) type, when substituted with lone pair bearing groups such as -O, -NH, and -S at the para positions, are theoretically shown to exhibit exopolyhedral multiple bonding on oxidation. Successive removal of two and four electrons from the parent B(n)H(n)(-)(2)X(2) results in highly varied and intriguing skeletal deformations that are explained using fragment molecular theory.

Conformations of Cyclohexane
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...
