Detailed explanation-1: -Dipole-Dipole Forces. Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule. Dipole-dipole forces have strengths that range from 5 kJ to 20 kJ per mole.
Detailed explanation-2: -Polar Covalent Bonds. A polar covalent bond exists when atoms with different electronegativities share electrons in a covalent bond.
Detailed explanation-3: -A polar molecule is called a dipole because it has two poles. Similarly, a polar bond itself can be called a dipole. A dipole is indicated by an arrow that starts on the positive end of the molecule and points to the negative end (see Figure below).
Detailed explanation-4: -Examples of a dipole–dipole interaction can be that between polar molecules, such as hydrogen chloride (HCl), carboxylic acids (i.e., acetic acid), and amino acids. The positive end of a polar molecule will attract the negative end of the other molecule and influence its position.
