(a) Interpretation: The change in concentration of FeCl 2 + due to the addition of Fe ( NO 3 ) 3 needs to be determined using Le Chatelier’s principle. Concept introduction: According to Le Chatelier’s principle, if equilibrium is disturbed by changing the number of moles, pressure and temperature, the equilibrium will shift to remove the disturbance. For example, if number of moles or pressure of reactant is increased, the reaction will shift in forward direction to decrease the number of moles or pressure of the reactant. If temperature is increased, the reaction moves to forward direction for an endothermic reaction and it moves to backward direction for exothermic reaction.

Calculate the proton and carbon chemical shifts for this structure
A.
B.
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?
