Identify which of the following molecules can exhibit hydrogen bonding as a pure liquid.Check all that apply.

You didn't provide the list of molecules to check. However, I can tell you the criteria for a molecule to exhibit hydrogen bonding:

1. The molecule must contain a hydrogen atom bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine). This is because these atoms pull the electron density away from the hydrogen atom, creating a dipole moment.

2. The molecule must also have a lone pair of electrons on the electronegative atom for the hydrogen atom of another molecule to bond with.

Please provide the list of molecules so I can help you identify which ones can exhibit hydrogen bonding.
