Solution
Solution Steps
Step 1: Identify the Intermolecular Forces in Isopropyl Alcohol
Isopropyl alcohol (C\(_3\)H\(_8\)O) is a polar molecule and contains an OH group. The presence of the OH group allows for hydrogen bonding. Additionally, as a polar molecule, it can also exhibit dipole-dipole interactions. All molecules exhibit dispersion forces (also known as London dispersion forces).
Step 2: List the Possible Intermolecular Forces
Dispersion Forces: These are present in all molecules due to the temporary fluctuations in electron density.
Hydrogen Bonding: This occurs because isopropyl alcohol has an OH group, which can form hydrogen bonds with other molecules containing N, O, or F atoms.
Dipole-Dipole Interactions: These occur because isopropyl alcohol is a polar molecule.
Step 3: Exclude Irrelevant Intermolecular Forces
Ion-Dipole Interactions: These occur between ions and polar molecules. Since isopropyl alcohol does not contain ions, this type of interaction is not relevant.
