Chemical Bonding: Molecular Orbital Theory-bonding
anti-bonding And non-bonding orbitals. Molecular orbital
diagrams for Hydrogen, Helium, Nitrogen, discussion of bond
order and magnetic properties. Nuclear Chemistry: Fundamental
particles – Istopes, Isobars, Isotones and Isomers-Differences
between chemical reactions and Nuclear reactions-group
displacement law. Nuclear binding energy-Mass
defect-calculations. Nuclear fission and nuclear
fusion-differences-Stellar energy. Applications of
radioisotopes-carbon dating, rock dating and medicinal
applications.
Unit – II: Industrial Chemistry

effect and consequences on Ka and Kb of organic acids and
bases, electrometric, mesomeric, hyper conjugation and
steric-examples.

Relation mechanisms: Types of reactions-aromaticity (Huckel’s
rule) – aromatic electrophilic substitution; nitration,
halogenation, Friedel-Craft’s alkylation and dacylation.
