1. The chromium-chromium bonding in a molecule uses the 3d orbitals of the chromium atoms. a. Draw the 3d orbitals of a chromium atom being sure to label the x, y and z axes. Standard convention is that the z-axis is parallel to the internuclear axis. b. Draw the MO energy diagram for an isolated [Cr2]2+ fragment (no ligands!) assuming the interactions of only the 3d orbitals. Assume that the z-axis is parallel to the internuclear axis c. Next to...
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...
In 1984, the first organometallic compounds with H2 as an ?2 ligand were synthesized: M(CO)3(PR3)2(H2) with M = Mo or W and R = cyclohexyl or isopropyl. These complexes illustrate back-bonding with H2 as a ligand. a. Draw a structure for this molecule (just use R for the substituents on the P atoms). Because the R groups are very bulky, assume that the two PR3 ligands are in a trans configuration. Only one isomer is then possible. Show that this...
VSEPR Objective : This lab is to study the shape and polarity of molecules using VSEPR theory with emphasis on sigma bonds (Part 1) and pi bonds and resonance (Part 2) Procedures: Nothing to do before the lab. We are making the models together in class. Prelab Questions : PART 1: (PL1) Draw the Lewis dot structure of each compound (as having covalent bonds). (a) BeH2 (b) BH3 (c) GeH2 (d) CH4 (e) NH3 (f) H2O (g) PCl5 (h)...
