🔴 Polarity of Bonds || Chemistry for Class 11 in HINDI

In this Chemistry video in Hindi for class 11 we explained polarity of chemical bonds and dipole moment in molecules. When two atoms of different electronegativity create a covalent bond the more electronegative atom attracts the shared pair of electrons and creates a dipole. A diple is a system of charges of equal magnitude but different natures and separated by a certain distance. When a molecule becomes a dipole, the molecule is called a polar molecule. e.g., water molecule; the dipole moment of water molecule is 1.85 D (debye units). We considered a lot of examples, like, BeF2, BF3, NF3, NH3.
