Solution
The molecule that contains a nonpolar covalent bond is O2.
Here's why:
A nonpolar covalent bond is a type of chemical bond where two atoms share a pair of electrons with each other. This occurs when the electronegativity difference between the two atoms is very small or zero.
A. HF - This is a polar covalent bond. Fluorine is more electronegative than hydrogen, so the shared electrons are more likely to be found around the fluorine atom.
B. O2 - This is a nonpolar covalent bond. Both atoms are oxygen, so they have the same electronegativity, and the electrons are shared equally.
C. CO - This is a polar covalent bond. Oxygen is more electronegative than carbon, so the shared electrons are more likely to be found around the oxygen atom.
D. NaCl - This is an ionic bond. Sodium (Na) is a metal and chlorine (Cl) is a nonmetal. Sodium donates an electron to chlorine, forming a positive Na+ ion and a negative Cl- ion. The attraction between these opposite charges forms the ionic bond.
