hydrogen bonding, dipole - dipole, and dispersion
dipole - dipole and dispersion only
dispersion only
answer bank
ch₄cl
ch₄
h₂o
co

Explanation:

Step1: Analyze $CH_4$

$CH_4$ is non - polar. It only has dispersion forces.

Step2: Analyze $CO$

$CO$ is polar. It has dipole - dipole forces and also dispersion forces (since all molecules have dispersion forces).

Step3: Analyze $CH_3Cl$

$CH_3Cl$ is polar. It has dipole - dipole forces and dispersion forces.

Step4: Analyze $H_2O$

$H_2O$ has hydrogen bonding (due to $O - H$ bonds), dipole - dipole forces (polar molecule), and dispersion forces.

Answer:

Hydrogen bonding, dipole - dipole, and dispersion: $H_2O$
Dipole - dipole and dispersion only: $CH_3Cl$, $CO$
Dispersion only: $CH_4$
