Question: what is the difference between polar covalent and covalent?
Answer: The difference between covalent and polar covalent bonds lies in the difference in electronegativity between the two atoms in the bond. ... In order for a bond to be called covalent, the difference in electronegativity must be less than 0.4 and for polar covalent bonds the difference must be between 0.4 and 1.7.
