The following molecules can exhibit hydrogen bonding as a pure liquid is NH3 (amonia), HC3 -- O -- OH (methanol), CH3CO2H (acetic acid)

Further explanation

Hydrogen bonding is directly connected to Nitrogen, Oxygen, and Fluoride and it (N, O, F) represents the hydrogen bonding. Whereas molecule is the smallest particle in a chemical element or compound that has the chemical properties of that element or compound

Identify which of the following molecules can exhibit hydrogen bonding as a pure liquid.

  1. NH3 (amonia) : Yes, because ammonia has 3 bonds, each between Nitrogen and a Hydrogen.
  2. HC3 -- O -- OH (methanol) : Yes, because oxygen and hydrogen in the hydroxyl group that branching off of the carbon share a hydrogen bond.
  3. CH2F2 (difluoromethane) : No, because the carbon bonds with two hydrogens and two fluorines, but hydrogen and fluorine never bond with each other.
  4. CF4 (tetrafluoromethane) : No, because the carbon bonds with four fluorine atoms, hence no hydrogen involved.
  5. HI (hydroiodic acid) : No, because F, O, N involved.
  6. CH3CO2H (acetic acid) : Yes, because hydrogen bonds with oxygen directly in the hydroxyl substituent group that forms off of the second carbon
  7. C7H6O (benzaldehyde): No, because this is a benzene ring with oxygen and hydrogen branching off of one of the carbons.

The molecules that exhibit hydrogen bonding are ammonia NH3, acetic acid CH3CO2H and H2C20H

What is hydrogen bonding?

Hydrogen bonding refer to am electrostatic force of attraction that exist between a hydrogen atom which is covalently bonded together to an atom that is more electronegative and another electronegative atom that have a lone pair of electrons. the hydrogen bond is the acceptor.

Therefore, The molecules that exhibit hydrogen bonding are ammonia NH3, acetic acid CH3CO2H and H2C20H.
