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.

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.
