which compound contains only a nonpolar covalent molecule?\no o₂\no hci\no h₂o\no no₃

which compound contains only a nonpolar covalent molecule?\no o₂\no hci\no h₂o\no no₃

Answer

Explanation:

Step1: Recall non - polar covalent bond concept

Non - polar covalent bonds occur between atoms with the same electronegativity.

Step2: Analyze each option

$O_2$: Two oxygen atoms have the same electronegativity. The bond between them is non - polar covalent.
$HCl$: Chlorine is more electronegative than hydrogen, so the bond is polar covalent.
$H_2O$: Oxygen is more electronegative than hydrogen, and the molecule has a bent shape, making it polar.
$NO_3^-$: Nitrogen and oxygen have different electronegativities, and the ion has a polar nature.

Answer:

$O_2$
