Question

How do you determine if a molecule is polar or non-polar?

Answer 1

the covalent bond are said to be polar when the shared pair of electrons are not at equal distance between the two atom.

covalent bonds are non polar when shared pair of electrons are equally distributed between the atoms

Answer 2

Step 2: Identify each bond as either polar or nonpolar. (If the difference in electronegativity for the atoms in a bond is greater than 0.4, we consider the bondpolar. If the difference in electronegativity is less than 0.4, the bond is essentiallynonpolar.) If there are no polar bonds, the molecule is nonpolar.
