Chapter 2 chemistry class 11 notes
Chapter two of Class eleven Chemistry deals with the concept of chemical bonding and defines how atoms hold together in molecules The chapter explains the transfer and sharing of electrons that lead to ionic and covalent bonds respectively Ionic bonding occurs when atoms exchange electrons creating positively and negatively charged ions that attract each other Covalent bonding happens when atoms share electrons to complete their outer shell achieving stability The chapter also outlines the various types of covalent bonds like single double and triple bonds and explains how bond length bond energy and bond strength are related Polar and nonpolar covalent bonds are introduced with examples and the concept of electronegativity helps explain why some bonds are polar while others are nonpolar Students learn to draw Lewis structures of simple molecules and ions based on the octet rule and can predict the molecular shape using VSEPR theory These concepts help in understanding the physical and chemical properties of substances and build foundation for studying advanced chapters in chemistry Let me know if you want notes on specific subtopics or examples under the same format
