Unformatted text preview: hat the 2p orbitals on the N and the O atoms are at the same energy; this is also not true in reality. Draw an energy level diagram (see diagram below) for the formation of the N‐O bond as I did in class for the H‐H bond. Indicate electrons with up and down arrows (spin up vs. spin down). Note that each p orbital can hold up to 6 electrons. The bonding and antibonding orbitals can also hold up to 6 electrons each. c) Indicate the energy splitting between the bonding and antibonding orbitals on the diagram. Assume that the antibonding orbital goes up by the same amount that the bonding orbital goes down with respect to the 2p orbitals /2. Updated 3/31/2011 10:36 PM d) Calculate the total bonding energy in terms of . Remember to account for the energy of all of the 2p electrons from both atoms before and after bonding. e) If the measured bond energy for the N‐O bond is 200 kJ/mol, estimate . f) Make a similar diagram for a C‐O bond. Assuming is the same for the N‐O and C‐O bonds, would we expect the bonding energy to be smaller or larger for C‐O? Why? 2) Gemanium was the first semiconductor used in transistors and radar in the 1940’s and 1950’s. Although it has some superior properties in terms of electron mobility, it was replaced by Si because it is difficul...
