Nonpolar covalent bonds

Definition

Nonpolar covalent bonds occur when two atoms share electrons equally, resulting in no distinct charge on either end of the bond. These bonds typically form between atoms of similar electronegativity.

5 Must Know Facts For Your Next Test

1. Nonpolar covalent bonds usually form between two identical nonmetal atoms.
2. Molecules with nonpolar covalent bonds are generally hydrophobic and do not dissolve in water.
3. Methane (CH4) is a common example of a molecule with nonpolar covalent bonds.
4. Nonpolar covalent bonding results in molecules that do not have partial positive or negative charges.
5. The strength of a nonpolar covalent bond is influenced by the distance between the bonded nuclei.
