Identify the intermolecular forces present in each of these substances. h2o co hcl co2

There are 4 general types of intermolecular forces: electrostatic force, London dispersion force, Dipole-Dipole force and Hydrogen Bonding.

Electrostatic force is the force between opposite charges; London dispersion force is common for nonpolar molecules, dipole-dipole forces common in polar molecules while hydrogen bonding is for molecules having either O-H, N-H and F-H bonds.

H₂O: Since water has 2 O-H bonds and it is polar, the intermolecular forces are hydrogen bonding and dipole-dipole forces

CO: It is polar sothe answer is dipole-dipole forces.

HCl: This is also a polar molecule, so dipole-dipole forces.

CO₂: This is a nonpolar molecules, so the answer is London dispersion forces.
