Study Notes
Naming Molecules
- Students must be able to name molecules using IUPAC or common nomenclature.
Compound Groups
- Thiols generally have a strong, unpleasant odor.
- CFCs were widely used as aerosol propellants and are known to deplete the ozone layer.
- Ethers were used as inhaled anesthetics during early surgeries.
Drawing Molecules
- Students must be able to draw the chemical structures of molecules. This includes benzanldehyde and trans-2-chlorocyclohexanol.
- For trans-2-chlorocyclohexanol, geometric details must be included in the drawing.
Solubility
- Students must be able to predict the solubility of a molecule based on its structure.
- For question 12, they need to determine if the given molecule is more soluble in water or methylene chloride.
Acidity
- Students must understand the concept of acidity and be able to identify the most acidic compound.
- They'll be given several compounds and asked to circle the one with the highest pKa (least acidic).
Identifying Unknown Compounds
- This question is a basic example of using IR spectroscopy and chemical tests (like the Tollens’ test) to help identify unknown compounds in a laboratory setting.
- To be completed successfully, students should be able to identify the most likely compound from a list and provide a justification for their choice.
CFC Structure
- Students need to understand the basic structure of a CFC compound.
- They will be given multiple structures and asked to select the one that best represents a CFC.
Alcohol Production of Alkenes
- Students need to be able to draw the structure of an alcohol that would produce the given alkene as a major product of a reaction.
- The reaction will be provided.
Keto-Enol Tautomerism
- Students must be familiar with keto-enol tautomerism and understand how a ketone group rearranges to form a different functional group.
- They will be asked to identify the functional group(s) that result from the rearrangement.
Identifying Hemiacetals
- Students must be able to identify the specific bonds and atoms that form a hemiacetal within a monosaccharide structure.
- They will be shown a monosaccharide hemiacetal and asked to circle the relevant bonds and atoms.
Fruity Breath Odor
- Students will need to explain why a patient might have fruity-smelling breath, even if they haven't eaten fruit.
- This requires understanding how the body processes different nutrients and what conditions can lead to the production of specific volatile compounds.
Fill-in-the-Box Reactions
- Students must be able to predict the products of chemical reactions.
- They will be given nine chemical reactions with one missing compound.
- The missing compound will be the reactant or the product of the reaction.
- Students must write the correct structure of the missing compound in the box provided.
- If no reaction occurs, they should write “NR” in the box.
- They will be given nine chemical reactions with one missing compound.
