Difference betweend polar and non polar bonds?

Answer 1

Non-polar bonds exist between 2 atoms that have the same electronegativity, which strictly only occurs when both atoms are the same. There is equal sharing of the bonding electron pair.

Polar bonds form between 2 atoms that have different electronegativities, and there is unequal sharing of the bonding electron pair. This gives the molecule a permanent electric dipole. This is important in understanding reaction mechanisms as one or other end of the molecule is often attracted to another species, initiating reactions.

Answer 2

Polar and non-polar bonds are types of covalent bond. A covalent bond is formed when two atoms share electrons. If the two atoms are identical, the bonding electrons will be shared equally, and the bond is described as non-polar. If the two atoms are not the same however, one atom can have a greater attraction for the shared electrons than the other atom. In this case the electrons will not be shared equally. One end of the bond will have a greater share of the electrons and will have a slight negative charge. The other end of the bond will have a smaller share of the electrons and so will have a slight positive charge. This type of bond, where there is a slight separation of electric charge, is called a polar bond. See http://www.elmhurst.edu/~chm/vchembook/144Acovalent.html this is a really good answer!

Answer 3

With Nonpolar Bonds, the electrons are shared equally, and the atoms are usually identical. With Polar Bonds, the electons are shared unequally which usually results inpartial charges.

Think of it this way, too. A Nonpolar bond is like two people of equal strength. A Polar bond is like two people that are enevenly matched, but are willing to share and help each other out.

Answer 4

In a polar bond, there is an unequal sharing of electrons between atoms due to differences in electronegativity, resulting in a partially positive and partially negative charge. In a nonpolar bond, electrons are shared equally between atoms because the atoms have similar electronegativities, leading to no separation of charge.

Answer 5

polar is a molecule that has two opposite ends or poles. Nonpolar is a molecule that does not have two opposite ends of poles.

Answer 6

Polar molecules dissolve in water while non-polar molecules, like fats and lipids, don't.
