1)Please explain backbonding with LFT (Use MO diagram)
and explain pi donor sigma donor pi acceptor by MO diagram
2) Are sigma donors included in all ligands?
=> strength of ligands :pi donor(with sigma donor) < sigma donor < pi acceptor(with sigma donoor)
Homework Answers
In backbonding, electrons move from one atomic orbital of one atom to another empty antibonding orbital on the other atom or ligand. It can be visualised as a type of resonance. Backbonding provides stability to the complex. Excess electrons from the metal get transferred to the ligand to make the metal get rid of the excess negative charge thus providing stability.
This type of bonding is mostly observed in CO ligands which is a sigma donor as well as pi- acceptor. The image attached depicts this bonding.

A bacterium can use H_2 as electron donor and either C_2Cl_6(aq) or SO_4(aq) as electron acceptor, according to the following reactions (equations not balanced): C_2Cl_6(aq) + H_2(g) = C_2Cl_4(aq) + H^+_(aq) + Cl^-_Which electron acceptor yields more free energy per mole of H2? For each reaction calculate the Delta_r G per mole of_H2 consumed under these conditions: 25 degree C, 1 atm, pH 7.0, and 1 mM for all aqueous species except H^+_(aq).
