Course Outcomes:

The concepts developed in this course will aid in quantification of several concepts in chemistry that
have been introduced at the 10+2 levels in schools. Technology is being increasingly based on the
electronic, atomic and molecular level modifications.
Quantum theory is more than 100 years old and to understand phenomena at nanometer levels, one has
to base the description of all chemical processes at molecular levels. The course will enable the student
to:

Analyse microscopic chemistry in terms of atomic and molecular orbitals and intermolecular forces.
Rationalise bulk properties and processes using thermodynamic considerations.
Distinguish the ranges of the electromagnetic spectrum used for exciting different molecular energy levels in various spectroscopic techniques.
Rationalise periodic properties such as ionization potential, electronegativity, oxidation states and electronegativity.
List major chemical reactions that are used in the synthesis of molecules.
