January 21, 2013 Semester Review: You can bring to the semester final a handwritten 3x5 card with any information you wish to help you on the exam. The following ideas and words may be helpful to you. Any or all of the following could be on your flashcards, however remember that you may not use your flashcards on the semester final. Review your notes, section All Material from first semester. Safety, Unit 1, Unit 2, and all class activities. For Unit 2: Identify all functional groups by molecular formula and structural formula. Recognize there may be isomers of these) Relate smell to functional group. R-C-O-O-H etc. Relate different smells to functional group. Classifying molecules. (shape, types of bonds, types of compound, polarity etc.) Carbon Hydrogen Oxygen Nitrogen Sulfur relationships within compounds Functional group type and characteristics such as: Carboxylic acids and names Ketone and name of substance Ether and name of substance Alcohol and name of substance Amine and name of substance Ester and name of substance Reaction of an acid and alcohol forming an ester Synthesis, synthesis reaction Prefixes in names telling how many carbons including but not limited to: Meth, Eth, Prop, But, Pent, Hex, Hept/Sept, Oct Smell such as: Iso Putrid, sweet, mint, medicinal, fishy, fruity, floral and proper usage. Sweet smelling include esters, ketones, and alcohols (be able to distinguish between shape and molecule) Minty smelling include ketones, alcohols (be able to distinguish between shape of molecule). ethanol, butanol, hexanol, isopentanol are examples of alcohols ethy alcohol, butyl alcohol, hexyl alcohol, methyl hexanol are another naming type of alcohols acetic acid, ethanoic acid, propanoic acid, butric acid, butanoic acid, heptanoic acid are examples of acids given in this unit Catalyst Lewis Structures, Lewis Dot two ways to show how electrons are being shared. HONC 1234 bond types/bond strengths in polar and nonpolar compounds How many functional groups have one oxygen and have no smell? Sharing of electrons vs giving taking of electrons (electronegativity and electronegativity difference) How many functional groups have one oxygen and have more than one smell? Shape of molecule, bond angles, unbonded electrons, bonded electrons Give the structural formula of Citronellol, L and D Carvone, Fenchol Single bonds, double bonds, triple bonds resonating bonds, symmetry, equivalence Covalent, Polar covalent To process the type/characteristics of a compound, determine/ask yourself questions such as: molecular shape--- long, stringy, pan shaped etc. molecular formula--- one oxygen, two oxygen, no oxygen, nitrogen, etc. functional group--- ester, carboxylic, amine, ether, alcohol, etc. smell--- putrid is carboxylic, fishy is amine, etc. Electron domains Receptor sites: what they do, size, shape, polarity Tetrahedral, Pyramidal, Trigonal Planar, Bent, Linear, Point Smells come from gases. What substances provide gases, Do not be fooled, solid substances such as D-carvone smells like caraway seeds (caraway seeds are solid), like rye bread and L-carvone is minty. Also liquids that are highly volatile have smell Polarity (nonpolar or polar) intermolecular force partial charges Number of carbons, numbers of hydrogens, long, stringy, frying pan, ball shaped 5-19 carbons long and stringy is sweet smelling, including fruity, floral smells 5 or less carbon alcohols are medicinal, 6 carbon chains that are flat are minty smell 6 carbon chains and ball shaped have camphor smell More than one carbon chain and one oxygen ball shaped is camphor smelling. Ethyl butyrate which is an acid and a liquid, smells like pineapple. You have other examples on your flashcards. January 21, 2013 Some diatomic elements that are small nonpolar gases, have a smell. So realize there are not solid rules or characteristics to go by. Water is polar and like most polar substances is an exception by not having a smell. Could this be why receptor sites dissolve in moisture to work? For Unit 1: Know all lab equipment and how to safely use. Know the safety rules. Review the Lab Safety Contract. Review notes of the material and placement of the safety material in the lab area. Know/recommend compound types from last semester and examples. (Ionic, Molecular Covalent, Metallic, and Network Covalent. Be able to define and write a hypothesis for an experiment. Mirror images, Mirror image isomers Understand the difference between physical, chemical and nuclear properties. Right/Left handed Definition of Chemistry Hydrophobic vs. Hydrophillic What is matter? Amino Acids Accuracy vs. precision and measuring of volume, length and mass. Proteins: shape, peptide bonds, chains of amino acids Define and work with equation for Density. Intensive vs Extensive properties Reactivity Writing Chemical equations. Reactants, states, balancing, yields, products Know the steps of the copper cycle used in the text. Handling of chemical substances including disposal by MSDS. Disposal of strong acids. Disposal strong bases. Reactions of Zinc, Copper, Nitric Acid, Nitrogen Dioxide, Copper II Nitrate, Sodium Hydroxide, Copper II Hydroxide, Copper II Oxide, Sulfuric Acid. Observations in the lab and class include qualifying, quantifying, safe use of senses and time. Oxidation states Writing lab reports. Lab report format. Data tables, conclusions based on data written in data table and observations. Atomic mass and amu. Be able to take a sample and determine amu. Protons, neutrons, electrons. Atomic Number. Trends and patterns that the periodic table is built upon. Electronegativity, Reactivity, Atomic number, alkali metals, alkaline earth metals, metalloids, metals nonmetals, actinides, lanthanides, main group elements, halogens periods, groups, families, noble gasses, transition metals, rare earth metals Naming of Ionic Compounds. Use of oxidation states, roman numerals for metals with multiple oxidation states. Rule of Zero Naming of nonmetal compounds. Use of prefixes Knowing/Using the polyatomic ions given in class to make "Happy" compounds. January 21, 2013 Atomic models and scientist: Solid Sphere (John DaltonP, Plum Pudding (J.J. Thomson), Nuclear Model (Ernest Rutherford), Solar System (Niels Bohr), Proton model (Ernest Rutherford), Electron Cloud (James Chadwick and Werner Heisenberg). Main ideas/theories accepted in each model. Isotopes Electron Configurations Energy levels, Principal Quantum levels Subshell Oribitals Electron directions or rotation Valence electrons Stable vs. Unstable Aufbau Principle Hunds rule Pauli Exclusion Principle Heisenburg Uncertainty Principle Alpha, Beta, Gamma Decay Cations compared to Anions Fission vs. Fusion Characteristics of Ionic compounds.
