What is the difference between polar and non polar covalent bonds?

1.	What is the difference between polar and non polar covalent bonds?
Answer» Polar covalent bond means there is electronegativity difference in the atoms forming covalent bond.for example HCI, H is electropositive in nature whereas Cl is electronegative .Non polar covalent bond means there is no electronegativity difference between the atoms forming covalent bond.for example Cl2\xa0 Ans.\xa0Polar covalent bonding\xa0is a type of chemical bond where a pair of electrons is unequally shared between two atoms. In a polar covalent bond, the electrons are not equally shared because one atom spends more time with the electrons than the other atom. In polar covalent bonds, one atom has a stronger pull than the other atom and attracts electrons. e.g. H2ONonpolar covalent bonds\xa0are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule. e.g. Cl2
