CY5012 : MAIN GROUP CHEMISTRY AND SPECTROSCOPIC CHARACTERIZATION OF INORGANIC COMPOUNDS

Course Objectives: The learners should be able to apply, analyze and evaluate the structure and bonding aspects of inorganic and organometallic compounds derived from main group elements, using spectroscopic techniques.

Learning Outcomes: At the end of the course, the learners should be able to:

Identify the basic principles related to structure and bonding of s & p block elements

Use various spectroscopic principles to characterize inorganic and organometallic compounds

Predict the synthesis and bonding properties of s and p block elements

Course Contents:
