CONTENTS :
UNIT I :
Ionic bonding - ionic crystals, NaCl amd CsCl crystal structure, Lattice energy and its determination using Born-Haber cycle, factors affecting crystal lattice energy, properties of ionic crystals (high melting point, hardness, electrical conductivity in molten condition and in solution) – ion polarization - Fajan’s rule-solubility of ionic compounds in polar solvent.

UNIT II :
Structure and shape of molecules : VSPER Theory and geometry of molecules. Hybridization and geometry of sp, sp2, sp3, dsp2, dsp3, d2sp3., sp3d2 and sp3d3. Bonding, shapes
and structures of the following molescules: Molccules with Sigma bonds only – BeCl2, SnCl2, BF3, CH4, SiF4, XeF4, PCl5, IF5, SF6,and IF7.

UNIT III :
Polar effects – inductive effect, mesomeric effect, electromeric effect, hyper conjugationand steric effects. Classification of reagents : Electrophiles, Nucleophiles and Free radicals.
Types of reaction : Polar reactions involving carbonium ions and carbanions with simple
examples.

UNIT IV :
Aliphatic Hydrocarbons : Restricted rotation about single bond preferred rotational
conformations.Alkenes: Preparation by Witting reaction – Mechanisms of beta elimination – E1, E2 and cis elimination – Hoffmanns rule and Saytzeff’s rule. Addition reactions with hydrogen, halogen, hydrogen halide (Markownikoff’s rule) and hydrogen bromide (Peroxide effect).

UNIT V :
1. Dienes : Stability of isolated and conjugated dienes-1, 2 and 1, 4 additions, Diels-Alder reaction. Free Radical addition – Polymerzation – synthetic rudder.
2. Cycloalkanes : Pre[aratopn by Dickmann ring closure and by reducation of aromatic hydrocarbons – ring opening reactions of cyclopropane with H2, Br2 and HI.
