Verified step by step guidance1
Understand the concept of bond polarity: A nonpolar covalent bond occurs when two atoms share electrons equally, typically between two atoms of the same element.
Identify the types of bonds: Nonpolar covalent bonds usually form between identical atoms, while polar covalent bonds form between different atoms with differing electronegativities.
Examine the given options: H-H, Na-Cl, O-H, and H-Cl.
Analyze the electronegativity: Hydrogen (H) atoms have the same electronegativity, leading to equal sharing of electrons in the H-H bond, making it nonpolar.
Compare with other options: Na-Cl is ionic, O-H and H-Cl are polar covalent due to differences in electronegativity between the atoms involved.
