Chapter Summary

--- PAGE 1 --- 11082CH04 UNIT 4 CHEMICAL BONDING AND MOLECULAR STRUCTURE Objectives After studying this Unit, you will be able to • understand 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; • explain 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. "Scientists are constantly discovering new compounds, orderly arranging the facts about them, trying to explain with the existing knowledge, organising to modify the ea…
