What characterizes a nonpolar covalent bond?

• A. A covalent bond in which the electrons are shared equally by the two atoms
• B. A covalent bond with unequal sharing of electrons
• C. A bond that cannot exist between identical atoms
• D. A bond that contains three pairs of electrons

Answer: (A)

A nonpolar covalent bond is characterized by the equal sharing of electrons between two atoms. This equality in sharing typically occurs between atoms of similar electronegativity, which means they have an identical ability to attract electrons. As a result, the electron density is evenly distributed, leading to a molecule that does not have distinct positive or negative poles. This is commonly observed in diatomic molecules composed of the same element, such as H2 or O2, where the electrons are equally shared, resulting in a stable bond without polar character. In contrast, other types of bonds indicate different relationships in electron sharing or bonding configurations, which do not apply to a nonpolar covalent bond.
