Study Notes
Molecular Structures
- A structural formula shows the arrangement of atoms in a molecule of a compound.
Representation of Carbon Atoms
- A zigzag or stick figure representation is used for carbon atoms in a bond-line structure.
Lewis Structure
- A Lewis structure shows the valence electrons, electron pairs, and bonds for each element in a molecule.
- It also shows the arrangement of electrons in a molecule.
Molecular Representation
- A condensed structure groups atoms of the same type bonded to one other atom together.
- It may not always show bonds.
Ring Structures
- A ring structure is a type of drawing where carbon atoms are joined together in rings.
Chemical Formula
- An empirical formula represents 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, cyclic compounds, and polygon formula. Learn about the different types of structural formulas such as Lewis structure, condensed structure, and skeletal structure.
