Study Notes
Chemical Bonding and Structure
- Magnetic quantum numbers determine the spatial orientation of atomic orbitals.
- Lewis electron dot diagrams display outermost electrons for bonding.
- Polar molecules like water are good solvents; nonpolar molecules like oils aren't.
- Polarity and cohesion are water's properties.
- Condensation polymerization creates polymers from monomers.
- Polyester examples are made from unsaturated hydrocarbons.
- Chemical reactions can form condensation polymers.
- BF3 has less than a full octet in its structure.
- Some molecules (like O2) are diamagnetic; others are paramagnetic.
- Carbon-carbon bonds in structures like polyester lead to high melting points.
- Amino acids make proteins.
Types of Molecules and Reactions
- Octet rules describe relative molecular stability.
- Covalent compounds like CCl4 are nonpolar.
- Starches are digested slowly.
- CO2 is nonpolar because of symmetrical charge distribution.
- Alcohols are R-OH.
- Ribose and deoxyribose are RNA and DNA sugars.
- Polymerization can form complex polymers.
- Terylene and complex carbs have similar bonding patterns.
- Boiling points for hydrocarbons increase with carbon chain length.
- Dehydration synthesis joins smaller molecules (like proteins, lipids & carbs).
