Here's a breakdown of the structure:

* CH3: This represents a methyl group (one carbon atom bonded to three hydrogen atoms).

* CH2: This represents a methylene group (one carbon atom bonded to two hydrogen atoms).

* NH: This represents an amino group (one nitrogen atom bonded to two hydrogen atoms).

The molecule consists of two ethyl groups (CH3-CH2) connected by an amino group.

Here are some key properties of diethylamine:

* It is a colorless liquid with a strong ammonia-like odor.

* It is flammable and volatile.

* It is used in various industrial applications, including the synthesis of pharmaceuticals, pesticides, and rubber chemicals.

Note: Diethylamine is a strong base and should be handled with caution. It can cause irritation to the skin, eyes, and respiratory system.
