CHEM120 OL, Week 5 Lab Name: Jasmine Albright CHEM120 OL, Week 5 Lab 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 carbon atoms 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: http://molview.org/ 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. Propane Virtual Model with Extended Structural Formula: Condensed Structural Formula: CH3CH2CH3 Butane Virtual Model with Extended Structural Formula: Condensed Structural Formula: CH3CH2CH2CH3 Ethylene Virtual Model with Extended Structural Formula: Ethyne Virtual Model with Extended Structural Formula:

CHEM120 OL, Week 5 Lab Name: Jasmine Albright Condensed Structural Formula: C2H4 or CH2=CH2 Condensed Structural Formula: CH3CH3 OR C2H6 Propyne Extended Structural Formula: Condensed Structural Formula: C3H4 or CH3CCH Ethane Virtual Model with Extended Structural Formula: Condensed Structural Formula: C2H6 or CH3CH3 Exploration 2: Identification of Functional Groups Part 2A: Building functional groups Functional groups alter the properties of hydrocarbons. Using the virtual resource build the extended structural formulas of the following compounds. Copy and paste the images into the space below. Alcohol: Ether Ketone

CHEM120 OL, Week 5 Lab Name: Jasmine Albright Carboxylic acid Aldehyde Ester Amine Part 2B: Identification of functional groups: Complete the table below by identifying the functional group s and names of the condensed structural formulas below. Condensed Structural Formula Name of Functional Group Name of Organic Molecule CH 3 CH 2 COCH 3 Ketone 2-Butanone CH 3 CH 2 CHO Aldehyde Propanal CH 3 OH Alcohol Methanol CH 3 CH 2 CH 2 CH 2 CH 2 NH 2 Amine Pentylamine CH 3 CH 2 CH 2 COOH Carboxylic acid Butanoic acid

CHEM120 OL, Week 5 Lab Name: Jasmine Albright Exploration 3: Building hydrocarbons containing functional groups Using the virtual resource build the extended structural formulas of the following compounds. Copy and paste the images into the space below. Difluoromethane Virtual Model with Extended Structural Formula: Trichloromethane Virtual Model with Extended Structural Formula: Tetrachloromethane Virtual Model with Extended Structural Formula: Propanol Virtual Model with Extended Structural Formula: Ethanoic Acid Virtual Model with Extended Structural Formula: Combine the propanol and the ethanoic acid from the last two exercises to make propyl ethanoate

CHEM120 OL, Week 5 Lab Name: Jasmine Albright Virtual Model with Extended Structural Formula: Phenol Virtual Model with Extended Structural Formula: Dimethyl ether Virtual Model with Extended Structural Formula: Condensed Structural Formula: CH 3 OCH 3 or C 2 H 6 O Propanal Virtual Model with Extended Structural Formula: Hexanoic acid Virtual Model with Extended Structural Formula: Condensed Structural Formula: C3H6O Condensed Structural Formula: C6H12O2 Ethylamine Virtual Model with Extended Structural Formula: Condensed Structural Formula: C2H5NH2 Questions:

CHEM120 OL, Week 5 Lab Name: Jasmine Albright Write the names of a biomolecule (also known as macromolecules) that contain each of the functional groups below. a. Amine - protein b. Aldehyde - carbohydrates c. Carboxylic Acid – fatty acid d. Alcohol - carbohydrates Find an example of an ester used as a fragrance or flavoring and give the name, condensed structural formula, and flavor of your chosen ester. Methyl salicylate has an odor and flavor wintergreen. The condensed structural formula is C8H8O3. For each of the following, give the functional group and application a. Formaldehyde – aldehyde, used as a preservative and for curing. b. Ethanol – alcohol, used as disinfectant, fuel, antiseptic. c. Acetone – ketone, used as a solvent for organic compounds. d. Phenol – hydroxyl, aromatic hydrocarbon used as disinfectant spray Reflection: Consider what you learned from this simulation. Reflect on three to four key concepts that you learned in this lab exercise. How could the lessons learned in this virtual lab relate to a real-world situation in the community/world or your future career? Be specific in your answer (this should require 5-10 sentences). This week’s simulation taught us how to recognize functional groups and determine their names based off physical characteristics of the structure (extended structural forms. Seeing and knowing where the atom bonds are placed made the task easier than I originally thought. As a future nurse it will be important to know chemical names and how to distinguish and pronounce them properly. While the simulation website made this task easier, it will still take a lot of practice before I can trust myself to successfully identify and draw each structure without assistance. Not too sure if this will be a part of my nursing career but having more knowledge about something doesn’t seem like a bad thing. I was not a huge fan of the virtual lab this week. The battery part was a little difficult and confusing, but I managed to figure it out. Knowing the charges of ions and their place in chemical reactions has great purpose in the real world. We use electricity and batteries for almost everything around us. While I don’t plan on fixing anything at my house if it breaks, having a certain amount of knowledge about it keeps me completely out of the dark on the situation.
