Interpretation: The hydrogen bonding between two ammonia molecules and one ammonia and one water molecule needs to be depicted.
Concept Introduction: A hydrogen bond is formed when a molecule with a hydrogen atom attached to an electronegative atom is near a molecule of the same and different kind having a hydrogen atom bonded to an electronegative atom.

Explanation of Solution
In an ammonia molecule, one nitrogen atom is bonded with three hydrogen atoms. Here, nitrogen has one lone pair of electrons. Here, the hydrogen bond is formed between two ammonia molecules. A hydrogen bond is formed when a molecule with a hydrogen atom attached to an electronegative atom is near a molecule with an electronegative atom bonded to a hydrogen atom. This type of hydrogen bonding between two same molecules is known as intramolecular hydrogen bonding.
Now, an ammonia molecule and a water molecule can also show hydrogen bonding. Here, a hydrogen atom from any one molecule can form a bond with the electronegative atom (oxygen and nitrogen) of another molecule. This type of hydrogen bonding between two different molecules is known as intermolecular hydrogen bonding.
