In this video, we'll learn how to draw the molecular, structural, and skeletal formulas for Dimethylamine (C₂H₇N).
Starting with the molecular formula, C₂H₇N, we see the number of Carbon, Hydrogen, and Nitrogen atoms, but it doesn't reveal their arrangement. However, this formula, along with the name "Dimethylamine," suggests it is a secondary amine, meaning the nitrogen atom is connected to two carbon atoms.
Next, we'll draw the structural formula for Dimethylamine, showing how the Carbon, Hydrogen, and Nitrogen atoms are connected. This provides a clearer picture of the molecule's structure, revealing a central nitrogen atom bonded to two methyl groups (CH₃) and one hydrogen atom.
Finally, we'll simplify the representation by drawing the skeletal formula, also known as the bond-line formula. This type of drawing only shows the Carbon backbone, with Carbon atoms implied at each vertex and endpoint. The Nitrogen and Hydrogen atoms would be explicitly shown in the skeletal structure.
Each of these representations-molecular formula, structural formula, and skeletal formula-offers unique insights into the molecule. By understanding how to draw and interpret these formulas, you'll be able to visualize molecular structures in organic chemistry.
