Which of the following can form Hydrogen bonding with each other?

Explanation

Option C is correct. Amines and water can form hydrogen bonds due to the presence of hydrogen atoms attached to the electronegative nitrogen in amines, which can interact with the oxygen in water. This interaction is crucial for many biological and chemical processes.In contrast, Option A (Methanal and Ethanol) cannot bond due to the lack of sufficiently electronegative hydrogen in methanal. Option B (Propane and Ethyl Methyl Ketone) involves nonpolar molecules that do not form hydrogen bonds. Lastly, Option D (Acetone and Acetaldehyde) fails to bond as neither has hydrogen directly bonded to an electronegative atom, preventing hydrogen bonding.
