Question

imagine that each substance below is in its pure form. match each of the substances with the strongest intermolecular force that could occur between its molecules. nh3 hbr n2 london dispersion forces dipole - dipole forces hydrogen bonding

Explanation:

• For \(NH_3\): It has \(N - H\) bonds. Hydrogen bonding occurs when \(H\) is bonded to \(N\), \(O\), or \(F\). So the strongest intermolecular force is hydrogen bonding.
• For \(HBr\): It is a polar molecule (\(Br\) is more electronegative than \(H\)). In polar molecules, the strongest intermolecular force (other than hydrogen - bonding if not applicable) is dipole - dipole forces.
• For \(N_2\): It is a non - polar molecule. The only intermolecular forces in non - polar molecules are London dispersion forces.

Answer:

\(NH_3\) - Hydrogen bonding; \(HBr\) - Dipole - dipole forces; \(N_2\) - London dispersion forces
