Chemical Bonding 11th

After studying this Unit, you will be
able to
• u n d e r s t a n d Kössel-Lewis
approach to chemical bonding;
• explain the octet rule and its
limitations, draw Lewis structures
of simple molecules;
• explain the formation of different
types of bonds;
• describe the VSEPR theory and
predict the geometry of simple
molecules;
• e x p l a in the valence bond
approach for the formation of
covalent bonds;
• predict the directional properties
of covalent bonds;
• explain the different types of
hybridisation involving s, p and
d orbitals and draw shapes of
simple covalent molecules;
• describe the molecular orbital
theory of homonuclear diatomic
molecules;
• explain the concept of hydrogen
bond.
