Organic Chemistry II Lab

Students complete at-home laboratory experiments, in addition to tracking and recording results, and take lab-based assessments to meet the lab requirement. eScience Labs, a leading provider of at home lab kits and supplemental online materials, provides the necessary labs.

Prerequisites

There are no prerequisites to take Organic Chemistry II Lab though we highly recommend concurrent enrollment in Organic Chemistry II (CHEM251) and previous completion of Organic Chemistry I (CHEM250) and Organic Chemistry I Lab (CHEM250L) or their equivalents.

Lab Objectives
Infrared Spectroscopy
  • Define infrared radiation and spectroscopy.
  • Relate vibrational energy to organic functional groups.
  • Explain how peaks are assigned to functional groups.
  • Explain how infrared spectra are solved.
  • Label peaks on infrared spectra.
  • Determine functional groups present in spectra.
Nuclear Magnetic Resonance
  • Describe spectrometry.
  • Define nuclear magnetic resonance, spin-spin coupling, and chemical shift.
  • Interpret the integration, multiplicity, and degrees of unsaturation in a spectrum.
  • Label multiplicity and number of hydrogens in a spectrum.
  • Recognize and label common functional group NMR patterns.
  • Determine molecular structure based on provided spectra.
Properties of Alcohols
  • Discuss the difference between ionic and covalent bonds.
  • Discuss the interactions between hydrogen bond donors and the acceptors in alcohols.
  • Explain boiling point trends for alcohols.
  • Describe functional group polarity and its relationship to solubility.
  • Describe classification of alcohols.
  • Label hydrogen bond donor and acceptors on alcohol-containing molecules.
  • Measure the solubility of seven alcohols in water and oil.
  • Relate molecular structure to the boiling points of two alcohols.
Isolation and Purification of Caffeine
  • Describe caffeine and its natural sources.
  • Define phase changes.
  • Discuss crystallization.
  • Explain chemical extraction.
  • Extract caffeine from a mixture.
  • Purify caffeine by sublimation.
  • Determine the percent isolation of caffeine.
Hydrolysis of Acetylsalicylic Acid
  • Describe the biochemical role of aspirin and other NSAIDs in the body.
  • Define the roles of the enzyme cyclooxygenase and prostaglandins in the body.
  • Identify commercially available NSAIDs and their uses.
  • Discriminate between drugs that are nonselective COX inhibitors and COX-2 inhibitors.
  • Define hydrolysis, condensation, and Le Châtelier’s Principle and apply these to the reactions involved in the synthesis of acetylsalicylic acid.
  • Outline common NSAIDs by identifying brand names, whether each drug is available only by prescription, typical uses, and which forms of the enzyme cyclooxygenase are inhibited by the drug.
  • Perform a hydrolysis reaction with acetylsalicylic acid and water, using iron(III) chloride to test for the presence of salicylic acid.
Synthesis of Fragrant Esters
  • Define esters as an organic functional group.
  • Discuss physical properties of esters.
  • Describe the IUPAC naming system for esters.
  • Use the IUPAC system to name a series of esters.
  • Synthesize fragrant esters by reacting a series of carboxylic acids and alcohols.
  • Relate the aroma and solubility of esters to their chemical structures.
Casein Extraction
  • Isolate, determine the quantity of, and test casein proteins extracted from milk.
  • Explain why proteins interact with metal ions in solution.
  • Describe how protein folding patterns are determined by different amino acid residues.
Isoelectric Point Titration/td>
  • Describe the amphoteric acidbase properties of proteins and their amino acids.
  • Explain how solution pH affects a variety of protein functional groups based on their pKa.
  • Find the pKa values and isoelectric point of an amino acid by titration with a strong base.

It was time for my next big thing.

Straighterline made it very easy and convenient to take all the prerequisites I needed to take to advance my career in Science. I liked how flexible it was. I would highly recommend it to anyone.

Things I love about StraighterLine

Time for me

I was able to fit classes into my free time and spend 10 hours a week when I was available.

Variety of courses

I took five courses with StraighterLine and saved thousands of dollars on my degree.
