CBSE Class 11 Chemistry Chapter 4 - Chemical Bonding and Molecular Structure

Chemical Bonding and Molecular Structure Class 11 Revision Notes

Chemical Bonding and Molecular Structure Class 11 Notes – The chapter discusses the Kossel’s first insight into the mechanism of formation of electropositive and electronegative ions. Also, it tells that the electrostatic attraction between ions is the cause of their stability. Hence, it gives the concept of electrovalency. Furthermore, the describe covalent bonding. Also, the chapter discusses the formation of enthalpy of lattice. Moreover, the chapter also teaches the important parameters associated with chemical bonds like bond length, bond angle, bond enthalpy, and many more.

Furthermore, the chapter describes that the number of molecules and polyatomic ions cannot be accurately dined by a single Lewis structure. Moreover, a resonance which is a very important concept is also explained. Besides, various other topics like the VSEPR model, valence bond, etc are also explained.
