Nonpolar Covalent Bond

non polar covalent bonds electrons shared equally

A nonpolar covalent bond is a chemical bond where electrons are shared equally between two atoms

Analogy – like a couple with a joint bank account.

NONPOLAR COVALENT BOND

The electrons are equally shared 

non polar covalent bonds atoms shared at equal distance

There is no charge separation (dipole moment) in a nonpolar molecule
Nonpolar molecules are hydrophobic

Hydrophobic molecules repel water

Nonpolar molecules generally do not dissolve in water.

 

  • Nonpolar molecules don’t become hydrated.
  • The molecules are insoluble or almost insoluble in water.
  • Example:  carbon-hydrogen or carbon-carbon hydrophobic bonds.
  • More examples: tristearin, or tristearoyl glycerol, a component of natural fats

Nonpolar covalent bond electronegativity scale

 

If the difference in electronegativity scale between two atoms is 0.5 or less, it is a nonpolar covalent bond.

An example of nonpolar bondCarbon to carbon forms non-polar covalent bonds

Nonpolar covalent bonds tend to form between two very similar atoms. Their difference in electronegativity value is small in comparison to atoms with stronger bonds.

An example of nonpolar covalent bond is a bond between two carbon atoms.
