In addition to interacting with s and p orbitals of ligands such as NH,, CN, etc., d orbitals can also interact with other d-orbitals, resulting in the formation of metal-metal bonds. Thus, for a simple metal dimer (i.e., ignoring any other ligands), we can envision the following interactions: M1M2 ? bond bond 8 bond where the o bond represents a face-to-face interaction between the two d orbitals. Considering only the d orbitals on each metal and taking the metal-metal bond...

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...

Sn2 reaction - sketching molecular orbitals
The equation can be seen in the picture. I was assuming it was an Sn2 reaction given the polar aprotic solvent and strong nucleophile.For b), I assumed that the question asked me to draw the orbitals as shown above (as opposed to orbital diagram) because it asked me to identify the HOMO and LUMO.I'm confused as to where SEt (-) attacks/how to draw the attack i.e. the reaction itself as both steps occur at the same time. Also I'm assuming...

5. Molecular orbitals are formed by the overlap of atomic orbitals. Thus, n atomic orbitals can combine (overlap) to form n molecular orbitals. In 1,3-butadiene there are four atomic p orbitals which can combine to form four 7 molecular orbitals. In ethene there are two atomic p orbitals which can combine to form two y molecular orbitals. The drawings below show the different ways in which the p orbitals of ethene and 1,3- butadiene can be combined to form the...
