Explanation:

The reaction of propylamine with water gives a hydrogen shift from water molecule to amine group of propylamine.

 

Further explanation:

Acids and bases can be defined in many ways based on different theories, which are as follows:

According to Arrhenius theory, acid is defined as the one which produces hydrogen ions in a solution, while the base is defined as the one which produces hydroxide ions in a solution. According to Bronsted–Lowry theory, the acid in the reaction donates a proton while a base is one that accepts a proton. According to Lewis theory, the acid in the reaction accepts a pair of electrons while a base donates a pair of electrons.

The propylamine contains amine group. Amine group is a basic group that can accept a proton from proton donor species because of the lone pair of nitrogen.

The water molecule has acidic hydrogen and thus water can behave as a proton donor molecule.

The water will release the proton to form and propylamine will accept the proton to form .

The complete reaction of propylamine with water gives a hydrogen shift from water molecule to amine group of propylamine as follows:
