Description

Learning Objectives:

Learn about structure of organic compounds by building models
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 with nonmetals by sharing electrons (covalent bonds). Most biomolecules as well as most drugs are classified as organic compounds. In this laboratory exercise, we will build models of organic compounds and draw extended structural formula of organic compounds.

Materials: Molecular Modeling Kit

Exploration 1: Hydrocarbons (Complete before class)

Part 1A: Definitions

Hydrocarbon:
Saturated hydrocarbon:
Unsaturated hydrocarbon:

Part 1B: Naming of Hydrocarbons

Linear hydrocarbons can be divided in three categories- Alkane, alkene and alkyne. Complete the table below for naming the linear hydrocarbons.

Part 1C: Building models of Hydrocarbons

Build models of the following hydrocarbons and draw their extended structural formulas in the given table. Your instructor will sign off on each set.

Exploration 2: Identification of Functional Groups

Part 2A: Building functional groups

Functional groups alter properties of hydrocarbons. Build models of the following functional groups and draw their extended structural formula. Your instructor will sign off on each set.

Part 2B: Identification of functional groups:

Complete the table below by identifying the functional group and name for the condensed structural formulas below.

Exploration 3: Building Hydrocarbons containing functional groups

Build models of the following and draw their extended structural formula. Your instructor will sign off on each section.

Propanol (Retain the model for future exercise)
Ethanoic Acid (Retain the model for future exercise)
Combine the propanol and the ethanoic acid from the last two exercises to make propyl ethanoate

Questions:

Find and give the name of biomolecules (also known as macromolecules) that contain each of the functional groups below.
Find an example of an ester used as a fragrance or flavoring and give the name, condensed structural formula, and flavor of this ester.
For each of the following, give the functional group and application

Reflection:

Reflect on 4 key concepts that you learned in this lab exercise. Be specific in your answer (this should require 10-12 sentences).
