The students will be able to –
CO126: describe LCAO concept and construct MO diagram of triatomic molecules and different types of complexes (octahedral, tetrahedral and square planar). CO127: explain thermodynamic with kinetic stability and compare between inert and labile complexes. CO128: Discuss SN2 mechanism in square planar complexes and apply the concept of trans effect to identify the cis and trans isomers. CO129: define, classify and name various organometallic compounds. Calculate valence electron count (18-electron). Discuss the preparation, properties, bonding and applications of organometallic compounds of some simple metals.
