b. Now consider the two bicyclic molecules A. and B. Note that A. is a dianion
and B. is a neutral molecule. One of these molecules is a highly reactive
compound first characterized in frozen noble gas matrices, that self-reacts
rapidly at temperatures above liquid nitrogen temperature. The other
compound was isolated at room temperature in the early 1960s, and is a
stable ligand used in organometallic chemistry. Which molecule is the more
stable molecule, and why?
