Strategies

On completion of this course, the students will be able to-

CO129: describe LCAO concept and construct MO diagram of triatomic molecules and  different types  of complexes (octahedral, tetrahedral and square planar).

CO130: explain thermodynamic with kinetic stability and compare between inert and labile complexes.

CO131: Discuss SN2 mechanism in square planar complexes and apply the concept of trans effect to identify the cis and trans isomers.

CO132: 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.

CO133: develop a general idea of catalysis and describe in detail the mechanism of various homogeneous and heterogeneous organometallic catalysts.

CO134: interpret the structure and bonding involved in metal carbonyls and metal nitrosyls.
