Polymerization

A process that joins two or more monomers together through a chemical reaction to create a larger molecule called a macromolecule.

Inorganic Macromolecules

Large molecules that are not primarily composed of carbon and hydrogen, often found in materials like rubber and certain plastics.

Protein Functions

Proteins have various functions including providing energy, acting as hormones, and forming structural components like hair, tendons, and ligaments.

Condensation Reaction

A chemical reaction where two smaller molecules combine to form a larger molecule, while releasing a small molecule like water.

Study Notes

Functional Groups in Organic Chemistry

  • Functional groups in organic chemistry include alkane, alkene, alkyne, alcohol, ether, aldehyde, ketone, carboxylic acid, ester, amide, amine, and alkyl halide.
  • Alcohols contain a carbon bound to an OH group and are named with the suffix "ol" or the prefix "hydroxy," with priority given when naming compounds.
  • Alcohols can be primary, secondary, or tertiary, with specific characteristics such as increased boiling points and flammability.
  • Ethers contain an oxygen atom between two carbon atoms and are named using individual chain names listed alphabetically with "ether" added afterward.
  • Diethyl ether, an important ether, has been historically used as a general anesthetic and revolutionized surgery in the 1800s.
  • Alkyl halides are carbons bound to halogens, named using the halogen as a prefix to the compound's name, and are important in various reactions and applications.
  • Ketones and aldehydes both have an oxygen atom double bonded to a carbon atom, with ketones having the formula R-CO-R' and aldehydes having the formula R-CHO.
  • Ketones and aldehydes are slightly polar, have specific solubility and reactivity properties, and play important roles in organic chemistry reactions.
  • Alcohols include compounds used as solvents, fuel sources, and in medication production, not just the organic compounds found in alcoholic beverages.
  • Ethers do not exhibit as strong intermolecular hydrogen bonding as alcohols, but diethyl ether, for example, has a historical significance in medicine as a general anesthetic.
  • Alkyl halides are used in various applications, including as refrigerants, propellants, and in the production of plastics and foams.
  • Functional groups play crucial roles in organic chemistry reactions and have specific properties that make them valuable in various applications and industries.
