  •  Introduction to Course

The brief description and learning objectives of this course include:

  1. The course is related to dipole moments, geometry of molecules, pi acceptor ligands and organic reagents used in inorganic analysis.   
  2. The primary objective is to teach the students about every concept in detail.
  3. The students will learn about the rules applied for determining geometries of known molecules and then will be able to apply them on molecules of interest.
  4. The students will understand about monodentate, bidentate type of molecules, chelates etc.
  5. They will learn about formation of metal complexes and the reagents for this application.
  6.  The students will understand what a pi-acceptor ligand is? and how the ligands donate and accept back the electron density from metals to form double-dond character and stabilize the molecules which are otherwise unstable. 
  7. They will learn the use of organic reageents for determinations and analysis of inorganic compounds.
