Download Chemistry Notes FSc-I (Pre-Engineering) PDF New Course FBISE Ch#3-Theories of Covalent Bonding and Shapes of Molecules

Dear Students and Respectable Parents / Teachers,

In third chapter (Ch#3-Theories of Covalent Bonding and Shapes of Molecules), the students will learn about define bond energy, relate bond energy with bond strength, define bond length, explain ionic character of covalent bond, predict the nature of bonding on the basis of electronegativity, describe the change in bond length of heteronuclear molecules due to the difference of electronegativity values of bonded atoms, explain dipole moment, predict geometry and dipole moment of different molecules on the basis of molecular theory;state the postulate of valence shell electron pair repulsion (VSEPR) theory, describe the shape of simple covalent molecules using VSEPR theory, explain and compare VBT and MOT, predict the electronic configuration, bond order and magnetic properties of homonuclear diatomic molecules with the help of MOT, explain hybridization and describe the shapes of simple molecules using orbital hybridization (sp, sp2, sp3), explain the solubility of ionic and covalent compounds on the nature of bonding, explain chemical properties of ionic and covalent compounds, compare directional and non-directional nature of ionic and covalent bonds.
