Study Notes
Angular Quantum Number of Carbon
- Carbon's electron configuration is 1s2 2s2 2p2
- The angular momentum quantum number for carbon is 1
Magnetic Quantum Number of Oxygen
- Oxygen has an atomic number of 8
- The magnetic quantum number for oxygen is not provided in the text, or not directly calculable from the provided information.
Hund's Rule and Paramagnetic Elements
- Hund's rule states that electrons fill orbitals with parallel spins before pairing up.
- A paramagnetic element is attracted to a magnetic field.
- Neon (atomic number 10), Lithium (3), Helium (2), and Argon (18) are given as options. Of these, only Lithium is paramagnetic; the other three are diamagnetic.
Aufbau Principle
- "Aufbau" means "building up" in German
- Aufbau Principle is a method for determining the electronic configuration of elements.
Diamagnetic Element Determination
- A diamagnetic element is repelled by a magnetic field.
- To determine a diamagnetic element from a table, one must look for an element with all paired electrons in its orbitals.
Orbital Diagrams
- To determine the orbital diagram for an element, refer to the periodic table
- Using the periodic table and the location of an element, which of the given choices are useful in making the correct diagram.
- To create a Lewis structure for Germanium (atomic number 32), determine its valence electrons and identify how electrons are shared or transferred in bonding.
Covalent Bonds
- To determine the element that forms a covalent bond, one must look at the position of the element in the periodic table, for if the element is a nonmetal, then it will form a covalent bond with another nonmetal.
Octet Rule Violations
- Some molecules violate the octet rule (e.g., molecules with odd numbers of electrons).
- To determine if a compound violates the octet rule, refer to the chemical formula or Lewis structure of the compound.
Molecular Formulas and Lewis Structures
- Molecular formulas and Lewis structures are visual representations of molecules.
- These molecular formulas and Lewis structures help to determine the exact type of compound, and how the molecules are put together.
Polar and Nonpolar Molecules
- Polar molecules have uneven charge distributions and do not mix well with nonpolar substances.
- Nonpolar molecules have even charge distributions and mix well with nonpolar substances.
- To differentiate between polar and nonpolar molecules, consider the polarity of their bonds and the molecular shape of the molecule.
Dissolving Substances in Water
- Substances that are polar are more likely to dissolve in water.
- Substances that are ionic or strongly polar are more likely to dissolve in water.
Functional Groups
- Functional groups are specific groups of atoms within molecules that determine how the molecule reacts.
- To identify functional groups, one need to observe the structure (or given description) of the compound/molecule.
- Examples include aldehydes, ketones, alcohols, ethers, and carboxylic acids.
Isomers
- Isomers are molecules with the same molecular formula but different structures.
- To identify isomers, study the molecular formula and structural drawings of isomers.
- Examples include butane and methylpropane.
Chemical Reactions
- Chemical reactions involve the breaking and forming of chemical bonds to change the composition of reactants into products.
- Some chemical reactions, like combustion, involve chemical changes to substances by heating.
Protein Structure and Function
- Proteins have a complex structure that determines their functions.
- Proteins are complex molecules that are composed of amino acids, which are linked together using peptide bonds.
- Important aspects of protein structure and function include the interaction of the amino acids and their sequence in the polypeptide chain determining the final structure, and therefore function.
- To determine the structural differences between different protein functions, inspect the structural differences between them, looking at the specific amino acid sequences, structure features and composition.
Lipid-Rich Foods and Rancidity
- Lipid-rich foods can become rancid due to oxidation of unsaturated fatty acids.
- This process breaks down the lipids within food items, changing the flavor, scent and texture of the food.
Fat Metabolism
- Fat metabolism involves processes like the synthesis of very-low-density lipoprotein (VLDL).
- Different factors like insulin levels, and presence or absence of energy sources can impact fat metabolism.
Diet and Health Conditions
- Following restrictive diets can lead to ketone formation, or potentially starvation as a result of nutrient deficiencies.
- It is recommended to consult with a professional before starting a new diet or nutrition plan.
Esterification and Organic Compounds
- Esterification is a chemical reaction producing ester compounds.
- The chemical structure of common organic compounds like ethanol and esters depend on the components used for synthesis - a process guided by particular chemical or physical conditions.
