Chapter Overview
Chemical Bonding is the third chapter of Class 9 Chemistry. It covers why atoms interact to form chemical bonds, describing the octet and duplet rules. Students learn the mechanisms of chemical bonding, including ionic bonds (electron transfer), covalent bonds (mutual electron sharing), and coordinate covalent bonds (one-sided sharing).
This chapter details the electropositive character of metals, the electronegative character of non-metals, and compares the physical and chemical properties of ionic and covalent compounds. Metallic bonding and the mobile electron model are also introduced.
Finally, the chapter covers intermolecular forces, describing dipole-dipole forces and hydrogen bonding, explaining how these weak attractions influence physical properties like melting and boiling points.
