The molecule that has a non-polar covalent bond is
HCl
\(NH_3\)
\(Cl_2\)
\(H_2O\)
Paliwanag
In \(Cl_2\), the two chlorine atoms are identical and have the same electronegativity. Since both atoms have the same electronegativity, the electrons in the covalent bond are shared equally, resulting in a non-polar covalent bond. The molecule does not have a significant separation of charge and lacks a permanent dipole moment.
