Chemical Bonding and Molecular Structure
Why do common salt and sugar behave so differently when dissolved, and why is diamond hard while graphite slides. This chapter in NCERT Class 11 Chemistry, Chapter 4, answers such questions through the ideas of ionic, covalent and coordinate bonds, Lewis structures, VSEPR shapes, valence bond theory and molecular orbital theory. It explains polarity, dipole moment, hydrogen bonding and the geometry of simple molecules. You will learn to predict bond order, bond length and the shapes of compounds from the arrangement of electrons around atoms.
