Study Notes

Carbon and Bonds

  • Carbon primarily forms covalent bonds with itself and other elements.
  • A single carbon atom can form four bonds.
  • Carbon readily bonds with elements of similar electronegativities.

Structural Features of Carbon Compounds

  • Catenation refers to carbon's ability to create long chains and rings of covalent bonds.
  • All organic compounds contain carbon, with exceptions such as oxides and carbonates.
  • Carbon monoxide (CO) is a classic example of a non-organic compound despite containing carbon.

Molecular Structure and Isomers

  • Molecular Formula indicates the number and types of atoms in a molecule without showing bonds.
  • Structural Formula displays how atoms are arranged and bonded.
  • Isomers are compounds with the same molecular formula but different structural arrangements.
  • Structural isomers are constitutional isomers that differ in the connectivity of atoms, while geometric isomers have the same connectivity but differ in spatial arrangement.

Hydrocarbons

  • Hydrocarbons are the simplest organic compounds composed solely of hydrogen and carbon.
  • They are categorized into saturated (single bonds only, e.g., alkanes) and unsaturated hydrocarbons (contain double or triple bonds, e.g., alkenes, alkynes).
  • The general formula for non-cyclic alkanes is CnH2n+2, while unsaturated compounds have different formulas based on their bonding arrangements.

Functional Groups and Their Reactions

  • Functional groups are specific groups of atoms that define the chemical reactivity of compounds.
  • Examples include hydroxyl (-OH) for alcohols and carbonyl (C=O) for aldehydes and ketones.
  • Substitution reactions involve replacing one atom or group in a molecule, typically forming alkyl halides from alkanes and halogens.
  • Addition reactions increase saturation—hydrogenation is a specific type that adds hydrogen atoms to unsaturated molecules.

Polymers

  • Polymers are large molecules made of many repeating units called monomers.
  • Main types include addition polymers (formed from monomers with double bonds) and condensation polymers (formed from monomers with two functional groups).
  • Condensation reactions typically produce water as a byproduct.

Common Uses and Properties

  • Ethers are commonly used as organic solvents.
  • Glycerol, a type of alcohol, is used for moisturizing properties.
  • Aromatic hydrocarbons, like benzene, have delocalized electrons and are characterized by six-membered carbon rings.

Key Characteristics of Organic Acids

  • Organic acids are generally considered weak acids and include compounds like carboxylic acids.
  • These acids commonly feature a carboxyl group (-COOH), giving them distinct properties.

Summary of Organic Compound Classes

  • Alkanes, alkenes, and alkynes differ in the types of bonds present, with respective suffixes of -ane, -ene, and -yne.
  • Functional groups dictate the reaction types and properties of organic compounds, crucial for identifying and classifying different organic families.
