What is the difference of non-polar and polar covalent bonds?

Answer 1

In a non polar covalent bond, the electrons that form the bond are equally attracted to each of the two nuclei that are bonded. In a polar covalent bond, the electrons that form the bond are more attracted to one of the two nuclei that are bonded than to the other. This uneven distribution of electric charge within the bond gives molecules with polar covalent bonds a permanent electrical dipole moment.

Answer 2

Polar covalent molecules have a defined axis (or defined axes) of partial positive and partial negative elements. The difference in all the electronegativities of each element should be between .4 and 1.7 inclusively. For example, H2O:



Non-polar covalent molecules do not have a defined axis of partial positive and partial negative elements. The difference in at least one of the electronegativities of at least 2 elements should be less than .4 exclusively. For example, CCl4:



Non-polar covalent molecules:
1.) Either have at least 1 bond between at least 2 elements as Non-polar covalent
2.) Do not have a defined axis (or axes) or partial positive and negative.


Polar covalent molecules, however, do.


Non-polar Covalent Bonds:
Difference of the electronegativities is < .4


Polar covalent bonds:
Difference of the electronegativities is >/= .4 and

Ionic Bonds:
Difference of the electronegativities is > 1.7

Answer 3

All covalent bonds involve the sharing of electrons between atoms. In non-polar covalent bonds, the electrons are shared equally. In polar covalent bonds, the electrons are not shared equally.

Answer 4

Electrons are shared unequally in a polar bond.

Answer 5

nonpolar covalent bonds is the sharing electrons equally as for the polar covalent bonds are the unequal sharing of electrons.
