Study Notes
Quantum Mechanical Model
- Electrons exist in 3D regions around the nucleus called atomic orbitals, not circular orbits.
- Atomic orbitals represent the probability of finding an electron.
- De Broglie proposed that electrons possess wave-particle duality.
- Heisenberg's uncertainty principle states that simultaneously knowing both electron position and velocity is impossible.
- Schrodinger's equation describes electron behavior as a wave, predicting probable electron locations.
- Atomic orbitals are also called "fuzzy clouds" representing regions of high electron probability.
- Different orbitals (s, p, d, f) have distinct shapes (spherical, dumbbell, etc.).
- s orbital=1, p orbital= 3, d orbital= 5 and f orbital=7.
- More electrons and larger atoms = more space occupied.
Atomic Orbitals
- Atomic orbitals are designated by letters (s, p, d, f), each with distinct shapes.
- S-orbitals are spherical
- P-orbitals are dumbbell shaped.
- Different orientations exist within d and f orbitals, describing these shapes.
Electron Configuration
- Electron configuration describes the arrangement of electrons within atomic orbitals, determining electronic properties.
Organic Compounds
- Organic compounds contain carbon and hydrogen.
- Other elements may also be present.
- Organic compounds can be categorized as natural, synthetic or both.
Functional Groups and Polymers
- Functional groups dictate a compound's chemical behavior. Different functional groups react similarly.
- Monomers bond to form polymers.
- Polymerization is the process of creating polymers from monomers.
- Polymers are large molecules made of repeating subunits.
Types of Organic Compounds
-
Hydrocarbons: Contain only carbon and hydrogen.
- Variations in bond type (double, triple) cause diverse properties.
- Alcohols: Glycerol is an example and used as a skin moisturizer
- Ethers: Used as solvents or anesthetics
- Carboxylic Acids: Found in fruits; Citric acid is a common example.
- Aldehydes: Formalin is a type of aldehyde used in preservation.
- Ketones: Acetone is a common solvent
- Esters: Often have fragrant aromas.
- Amines: Characteristic, often unpleasant odors.
- Amides: Found in materials like nylon, silk, and wool.
- Alkyl Halides: Component of Teflon's non-stick properties.
- Alkanes: Simplest hydrocarbons - single bonds.
- Alkenes: Contain carbon-carbon double bonds.
- Alkynes: Have carbon-carbon triple bonds.
- Methanol: Also known as wood alcohol. Produced through heating wood in the absence of air
- Organometallic Compounds: Contain metals.
- Organophosphorus Compounds: Contain phosphorus.
