Textbook Question

Draw condensed and skeletal structures for each of the following amines: (b) N-ethylethanamine

Verified step by step guidance

Identify the parent amine structure. In this case, the parent amine is ethanamine, which has the structure CH3CH2NH2.

Recognize the substituent attached to the nitrogen atom. Here, the substituent is an ethyl group, which is CH3CH2.

For the condensed structure, combine the parent amine and the substituent. The condensed structure for N-ethylethanamine is CH3CH2NHCH2CH3.

For the skeletal structure, draw the carbon backbone as a zigzag line. Each vertex represents a carbon atom, and the nitrogen atom is connected to the appropriate carbon.

Ensure that the nitrogen atom is bonded to the ethyl group and the ethyl group is represented as a line extending from the nitrogen in the skeletal structure.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Amines

Amines are organic compounds derived from ammonia (NH3) by replacing one or more hydrogen atoms with alkyl or aryl groups. They can be classified as primary, secondary, or tertiary based on the number of carbon-containing groups attached to the nitrogen atom. Understanding the structure and classification of amines is essential for drawing their condensed and skeletal forms.

Condensed Structures

Condensed structures are a simplified way of representing molecular structures where bonds are implied rather than explicitly drawn. In these structures, atoms are listed in a linear format, showing how they are connected without depicting every bond. For amines, the condensed structure will show the nitrogen atom bonded to its substituents, providing a clear view of the molecular composition.

Skeletal Structures

Skeletal structures, also known as line-angle structures, are a shorthand representation of organic molecules where carbon atoms are represented by vertices and hydrogen atoms are often omitted for clarity. Each vertex represents a carbon atom, and the bonds are drawn as lines. This method is particularly useful for visualizing larger molecules like amines, as it simplifies the depiction of complex structures.
