Provide an example of the nucleophilic substitution of different amines.

An example of nucleophilic substitution of different amines is the reaction between ethanolic ammonia and 1-bromopropane.

Nucleophilic substitution is a type of organic reaction where a nucleophile replaces a leaving group in a molecule. In the case of amines, the nucleophile is usually an amine molecule that replaces a halogen atom in an alkyl halide. For example, when ethanolic ammonia reacts with 1-bromopropane, the bromine atom is replaced by an amino group, resulting in the formation of propylamine.

The reaction between ethanolic ammonia and 1-bromopropane is a primary nucleophilic substitution reaction. This means that the nucleophile attacks the carbon atom that is directly attached to the leaving group. The reaction proceeds through a transition state where the carbon-bromine bond is partially broken and the carbon-nitrogen bond is partially formed.

The reaction rate of nucleophilic substitution reactions depends on several factors, including the nature of the nucleophile, the leaving group, and the solvent. For example, primary amines are generally more reactive than secondary or tertiary amines because they have a higher electron density and are better nucleophiles.

In conclusion, the nucleophilic substitution of different amines is a common organic reaction that involves the replacement of a halogen atom in an alkyl halide with an amino group. The reaction rate and mechanism depend on several factors, including the nature of the nucleophile, the leaving group, and the solvent.
