Study Notes
Types of Formulas
- A structural formula shows the arrangement of atoms in the molecule of a compound.
- A Lewis structure shows the valence electrons for each element.
Molecular Structure
- A dash structure groups together atoms of the same type bonded to one other atom.
Representation of Molecular Structure
- A stick figure or line-angle structure represents the skeletal structure of a molecule.
Carbon Compounds
- When carbon atoms are joined together in rings, cyclic compounds are formed.
Simplest Ratio Formula
- An empirical formula shows the simplest whole-number ratio of the elements in a compound.
Test your knowledge of drawing organic compounds, including empirical formula, molecular formula, structural formula, perspective drawing, and cyclic compounds. Understand the different types of structural formulas such as Lewis structure, condensed structure, and skeletal structure.
