We’re being asked to identify the intermolecular forces present in each compound. Recall that there are several types of intermolecular forces:
1. Ion-dipole interaction – occurs between an ion and a polar covalent compound
2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F
3. Dipole-dipole interaction – occurs between two polar covalent compounds
4. Induced-dipole interaction – occurs when a nonpolar compound interacts with a polar compound
5. Dispersion forces – occurs in all compounds. This is the primary intermolecular force exhibited by nonpolar compounds.
For this problem, we need to do the following steps:
Step 1: Determine the central atom in the molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Step 4: Determine the polarity and IMF of the molecule.
Classify each substance based on the intermolecular forces present in that substance.
H2O, CO, H2, HCl
