OL Lab 9: Building models of organic
compounds Learning Objectives:
• Build virtual models to learn about the structure of organic compounds
• Draw extended structural formulas of organic compounds
Compounds that are based on the carbon atom are known as organic
compounds. These compounds commonly contain, nitrogen, oxygen, and
hydrogen in addition to carbon. Carbon forms a variety of covalent
compounds with varied properties. Carbon containing compounds are
formed by sharing electrons, covalent bonds, between atoms. Most
biomolecules, as well as most drugs, are classified as organic compounds. In
this laboratory exercise, you will build models of organic compounds virtually
and draw the extended structural formula of organic compounds.
Online Modeling Resource:
Note: Be sure to build each of the compounds as instructed using the online
modeling resource kit. This hands-on experience is an important part of this lab.
You will need to copy the models you build in the virtual modeling resource and
paste the images into this document. Please take the time to explore the
structures of these organic compounds.

Exploration 1: Building models of Hydrocarbons
Hydrocarbons are a diverse group of organic compounds containing carbon
and hydrogen. Hydrocarbons can be linear, branched, or cyclic. Additionally,
hydrocarbons can be saturated, unsaturated or aromatic.
Using the virtual resource build the extended structural formulas of the
following compounds. Copy and paste the images into the space below.
Additionally, type in the condensed structural formula.
