Organic Chemistry - Structural Representations

Description:

There are 4 common ways of representing structures of organic compounds.

• Dash structural formula
• Condensed structural formula
• Bond line structural formula
• 3-D structural representation

Example: C₃H₈O (CH₃CH(OH)CH₃)

Dash Structure − is obtained from Lewis dot structure of the compound, where the atoms are linked by lines.

Condensed Structure − the hydrogen atoms are written next to carbon atom.

Bond Line Structure − carbon skeleton with only heteroatoms like O,N,Cl are written.

3-D Representation − shows the placement of atoms in space.

• Solid wedge represents the atom coming out of the plane or towards the viewer.

• Dashed wedge represents the atom moving into the plane or away from the viewer.
