What type of chemical bond involves the equal sharing of electron pairs between two atoms of similar electronegativity?

The question describes a chemical bond formed by the equal sharing of electron pairs between two atoms with similar electronegativity.

• Ionic bonds involve the transfer of electrons, not sharing, and occur between atoms with a large difference in electronegativity.
• Hydrogen bonds are intermolecular forces, not chemical bonds.
• Polar covalent bonds involve the unequal sharing of electrons due to a moderate difference in electronegativity.
• Non-polar covalent bonds involve the equal sharing of electrons between atoms with very similar or identical electronegativity.

Based on the definition, the correct answer is C.

The correct answer is C.

$$\boxed{\text{C. Non-polar Covalent bond}}$$
