Identify the requirement for hydrogen bonding: A molecule must have a hydrogen atom directly bonded to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F).
Examine each compound to determine if it meets the criteria for hydrogen bonding.
For CCl4, note that it contains carbon and chlorine atoms. Since there is no hydrogen atom bonded to an electronegative atom, CCl4 does not exhibit hydrogen bonding.
For N2, recognize that it is a diatomic molecule consisting of two nitrogen atoms. There are no hydrogen atoms present, so N2 does not exhibit hydrogen bonding.
For NH3, observe that it contains nitrogen bonded to hydrogen atoms. Since nitrogen is a highly electronegative atom, NH3 can form hydrogen bonds. Therefore, NH3 exhibits hydrogen bonding as one of its intermolecular forces.
