Which statement describes nonpolar covalent bonds?

• A. Polar covalent bonds involve equal sharing.
• B. Nonpolar covalent bonds involve equal sharing.
• C. Ionic bonds involve electron transfer.
• D. Metallic bonds involve delocalized electrons.

Answer: (B)

Nonpolar covalent bonds occur when two atoms have very similar electronegativities, so the shared electrons are distributed nearly equally between them. Because the electrons spend roughly the same time near each nucleus, there’s no net charge separation and no dipole moment. This equal sharing is what the statement describes. In contrast, polar covalent bonds involve unequal sharing and create partial charges, ionic bonds involve electron transfer, and metallic bonds involve delocalized electrons in a lattice. So describing nonpolar covalent bonds as involving equal sharing correctly captures the essential idea.
