Ultimately a stage is reached when the enthalpy of the system becomes minimum and hydrogen atoms are said to be bonded together to form a stable H 2 molecule (state C). An example of a molecule with this configuration is boron trifluoride (BF 3), which has three F-B bonds, each forming 120-degree angles. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The theory centers around the idea that the clouds of electrons that surround nuclei and flow in the bonds that link atoms together repulse each other. Therefore, it gives information about different molecules which have the same constitution. Notice that compounds with the same number of terminal atoms, BF 3 and NF 3, do not necessarily have the same geometry. An [math] sp^3 [/math] carbon can form four [math] \sigma [/math] bonds. D. 3. The four fluorine atoms occupy different positions around bromine giving it a planar shape while occupying four corners. The existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities.
