Final answer:
The type of group that will NOT generate hydrogen bonds is C-H.
Step-by-step explanation:
Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom is bonded to a highly electronegative element such as nitrogen (N), oxygen (O), or fluorine (F). These three elements are able to form hydrogen bonds because they have a strong partial negative charge that attracts the hydrogen atom of another molecule.
In the given options, F-H, O-H, and N-H all have hydrogen atoms bonded to highly electronegative elements and therefore are capable of forming hydrogen bonds. On the other hand, C-H bonds involve a hydrogen atom bonded to a carbon atom, which is not electronegative enough to generate hydrogen bonds. So, the correct answer is D. C-H.
