If the two atomic orbitals represented below combine in phase in the orientation shown, which of the following statements is true?
If the two atomic orbitals represented below combine in phase in the orientation shown, which of the following statements is true? Removing an electron from the resulting orbital will increase bond order. The molecular orbital that results will have pi symmetry. The molecular orbital that results will have sigma symmetry. The molecular orbital that results will be an antibonding orbital. Removing an electron from the resulting orbital will decrease bond order. The molecular orbital that results will be a bonding orbital.

Assuming that only the valence orbitals are involved in bonding, draw an approximate MO energy-level diagram describing the relative energies of these eight molecular orbitals in N2. What is the apparent bond order for N2? Are there any unpaired electrons in this molecule? If so, how many? (Have all small details sigma,pi etc)
Mixing of s and p orbitals can lead to some strange effects and very unstable structures...
Mixing of s and p orbitals can lead to some strange effects and very unstable structures that cannot be accurately described using Lewis structures. We can even predict properties of molecules that have never been and may never be made! For each part, name a 2p homonuclear diatomic (e.g. Li2, N2, Ne2, etc.) that each statement represents. Draw an MO diagram supporting your choice. a) A molecule that has a double bond formed from two π molecular orbitals and zero...

Consider two 2p orbitals, one on each of two different atoms, oriented side-to-side, as in the figure. Imagine bringing these nuclei together so that overlap occurs as shown in the figure. This overlap results in a system of molecular orbitals. (Scroll down to answer part "c)".) a) Below, construct an orbital interaction diagram for molecular orbital formation by dragging the images triat represent various orbital types (e.g., atomic, bonding, antibonding) into the relevant boxes. b) Identify the number of nodes in each...
