Explanation:

• For \(N_2\):
• Nitrogen (\(N\)) has the same electronegativity in \(N - N\) bond. There is no charge separation. So, \(N_2\) is non - polar.
• For \(I_2\):
• Iodine (\(I\)) has the same electronegativity in \(I - I\) bond. There is no charge separation. So, \(I_2\) is non - polar.
• For \(NO\):
• Nitrogen (\(N\)) and oxygen (\(O\)) have different electronegativities (\(O\) is more electronegative than \(N\)). There is a charge separation (\(N^{\delta+}-O^{\delta -}\)). So, \(NO\) is polar.
• For \(HCl\):
• Chlorine (\(Cl\)) is more electronegative than hydrogen (\(H\)). There is a charge separation (\(H^{\delta+}-Cl^{\delta -}\)). So, \(HCl\) is polar.

Answer:

• Polar: \(NO\), \(HCl\)
• Nonpolar: \(N_2\), \(I_2\)
