Characteristics of Organic Molecules

Characteristics of Organic Molecules

• Contain carbon and hydrogen atoms, and may also contain other elements like oxygen, nitrogen, and sulfur
• Typically have a complex, non-repeating structure
• Are often found in living organisms, but can also be synthesized in a laboratory
• Can range in size from simple molecules like methane (CH4) to complex biomolecules like proteins and DNA

Types of Organic Molecules

• Hydrocarbons: contain only carbon and hydrogen atoms
  • Saturated hydrocarbons (e.g. methane, ethane) have only single bonds between carbon atoms
  • Unsaturated hydrocarbons (e.g. ethene, ethyne) have one or more multiple bonds between carbon atoms
• Functional groups: specific groups of atoms that determine the chemical properties of a molecule
  • Examples: hydroxyl (-OH), carboxyl (-COOH), amino (-NH2)
• Biomolecules: organic molecules that occur naturally in living organisms
  • Examples: carbohydrates, proteins, lipids, nucleic acids

Properties of Organic Molecules

• Solubility: organic molecules can be soluble in a variety of solvents, including water, hexane, and ethanol
• Boiling point: depends on the size and shape of the molecule, as well as the strength of intermolecular forces
• Reactivity: organic molecules can undergo a wide range of chemical reactions, including combustion, oxidation, and substitution

Importance of Organic Molecules

• Biological significance: many organic molecules are essential for life, such as carbohydrates, proteins, and lipids
• Industrial applications: organic molecules are used in the production of fuels, plastics, and pharmaceuticals
• Environmental impact: organic molecules can play a significant role in environmental processes, such as the carbon cycle and the formation of ozone.
