1. Draw the molecular orbital diagrams for \( \mathrm{N}_{2}, \mathrm{N2}^{+} \), and \( \mathrm{N}_{2}{ }^{2-} \). Then, write \( 1-3 \) sentences explaining which is more stable and why. You must be direct, detailed, and use the language learned in class to receive credit for your explanation. Please limit your explanation to 3 complete sentences, bullet points won't receive credit. You only need to include the valence shell in your drawings. You must draw in all electrons and label all orbitals to receive credit. \( 254 \ldots \cdots+\sigma^{*} \) \( 5 / 5 \) \( 254 t \ldots \ldots t_{0}^{*} \ldots \ldots=t_{2 s} \) \( \mathrm{N}^{2} \) \( 254=\cdots \cdot-45 \) tow.... \( =4 \), 25 \( \mathrm{N}_{2} \) is most stable because all electrons are placed in bonding molecular orbitals. \( \mathrm{N}_{2}{ }^{+} \)is less stable than \( \mathrm{N} 2 \) because one of its bonding molecular orbitals has an unpaired electron. \( \mathrm{N}^{2-} \) is the least stable because it has 2 electrons placed in antibonding molecular orbitals.

Draw the molecular orbital diagram, including the electrons, and write the electron configuration of $\mathrm{He}_{2}^{2+}$. Give the bond order and the number of unpaired electrons, if any. Is this a stable species?
Consider the $\mathrm{H}_{2}^{+}$ ion. (a) Sketch the molecular orbitals of the ion and draw its energy-level diagram. (b) How many electrons are there in the $\mathrm{H}_{2}+$ ion? (c) Write the electron configuration of the ion in terms of its MOs. (d) What is the bond order in $\mathrm{H}_{2}^{+} ?$ (e) Suppose that the ion is excited by light so that an electron moves from a lower-energy to a higher-energy MO. Would you expect the excited-state $\mathrm{H}_{2}^{+}$ ion to be stable or to fall apart? (f) Which of the following statements about part (e) is correct: (i) The light excites an electron from a bonding orbital to an antibonding orbital, (ii) The light excites an electron from an antibonding orbital to a bonding orbital, or (iii) In the excited state there are more bonding electrons than antibonding electrons?
