Solution: Classify the species given below by the intermolecular forces present in a pure sample of each:Ar H2 HCN HF BrCl5 NH3 CH3OH H2S PF5 CH2Cl2Are they dispersion, dipole-dipole, or H-bond?

Problem

Classify the species given below by the intermolecular forces present in a pure sample of each:

Ar H2 HCN HF BrCl5 NH3 CH3OH H2S PF5 CH2Cl2

Are they dispersion, dipole-dipole, or H-bond?

Solution

We’re being asked to identify the intermolecular forces present in each compound. Recall that there are several types of intermolecular forces:

1.  Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F

2. Dipole-dipole interaction – occurs between two polar covalent compounds
