ANATOMY

Detailed explanation-1: -In some polar molecules that contain hydrogen atoms, the partial positive charge of the hydrogen atoms of one molecule are attracted to the partial negative charge of an atom of a nearby molecule. This force of attraction is called a hydrogen bond.

Detailed explanation-2: -Hydrogen bonds are attractions of electrostatic force caused by the difference in charge between slightly positive hydrogen ions and other, slightly negative ions.

Detailed explanation-3: -Explain why and which part of a polar molecule can possibly form hydrogen bonds with other polar molecules while those with nonpolar covalent bonds cannot form such H-bonds.

Detailed explanation-4: -Polar Covalent Bonds A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal. In a polar covalent bond, sometimes simply called a polar bond, the distribution of electrons around the molecule is no longer symmetrical.

Detailed explanation-5: -Polar molecules attract water molecules, mainly through hydrogen bonding. They compete successfully with hydrogen bonds between the water molecules, so they are readily soluble in water.
