Textbook Question

Convert the following models into line drawings (back = C; white = H; blue = N):
a.

Verified step by step guidance

Identify the elements in the molecular model: Carbon (C) is represented by black spheres, Hydrogen (H) by white spheres, and Nitrogen (N) by blue spheres.

Determine the connectivity of the atoms in the model by observing how the spheres are bonded to each other. Single bonds are represented by one connection, double bonds by two, and so on.

Translate the 3D structure into a 2D line drawing. Represent carbon atoms as vertices or endpoints of lines, and omit hydrogen atoms bonded to carbon for simplicity (assume implicit hydrogens).

Include all heteroatoms (e.g., Nitrogen) explicitly in the line drawing and show their bonds. For Nitrogen, write 'N' at its position and include any hydrogens bonded to it explicitly.

Double-check the line drawing to ensure it accurately represents the molecular structure, including the correct number of bonds and atom placements.

Key Concepts

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

Line Drawings

Line drawings are simplified representations of objects or models using only lines to convey shape and structure. In the context of molecular models, line drawings typically depict atoms as points and bonds as lines, allowing for a clear visualization of molecular geometry and connectivity without the clutter of three-dimensional representations.

Color Coding in Chemistry

Color coding is a common practice in chemistry to represent different elements in molecular structures. For instance, carbon (C) is often represented in black, hydrogen (H) in white, and nitrogen (N) in blue. This system helps in quickly identifying the types of atoms present in a molecule and understanding its composition and structure.

Molecular Models

Molecular models are physical or visual representations of molecules that illustrate their structure, composition, and spatial arrangement. These models can be ball-and-stick, space-filling, or line drawings, each providing different insights into molecular interactions and properties. Understanding how to convert these models into line drawings is essential for accurately depicting molecular relationships.
