Metal-hydrogen complexes (M-H2) can exist as either (1) o-hydrogen or (11) dihydride complexes Draw an example of each type of complex List the factors which determines whether a complex of type (1) or (11) is formed Discuss the bonding between a nitrosyl (NO') ligand and a metal centre Specify whether the ligand is a 6-donor, n-donor-, Tt-acceptor or a combination of these Illustrate your answer with suitable orbital interaction drawings
An antibonding molecular orbital ______. a)results from the addition of the wave functions b)is lower in energy than a bonding molecular orbitals c) results from destructive interference between atomic orbitals d) has increased electron density in the internuclear region
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...
7. Rank the following ligands from strongest to weakest metal-ligand bond strength. | F, CH,CO2, NHẠC,H,NH, CÓ 8. In many cases, a transition metal ion is colored because the metal ion has an electron residing in a d-orbital that absorbs energy and is promoted to a higher energy d-orbital. The energy difference between the d-orbitals depends on the metal ion and the ligand. The complexes Co(NH3)2+ and Co(H20) 2+ are colored, one is red and one is yellow. Predict which...
- Why does it take energy to remove an electron from a metal surface? - Why are no electrons emitted from the surface of a metal if the frequency of light is below a threshold value? - How does application of the conservation of energy explain the dependence of electron kinetic energy upon the frequency of light shone on the metal surface. The subject is Physical CHEM ; Quantum mechanics
Why does the voltage of a battery go up sharply when it gets close to being fully charged and down sharply when it is close to fully discharged?
Why does the signal on an FM radio station often fade out as you go under a metal underpass on the freeway, but an AM station does not?
