Study Notes

Organic Compounds

  • Formed by carbon
  • Formed by the union of elements in the periodic table
  • Held together by covalent bonds

Carbon Characteristics

  • Forms concatenations (chains)
  • Primarily forms covalent bonds
  • Not present in all compounds

Compound Properties Comparison

  • Compound A: Low melting point (-28.15°C), insoluble in water
  • Compound B: High melting point (851°C), soluble in water
  • A is organic, B is inorganic

Isomerism

  • Carbon atoms can form different spatial arrangements of molecules with the same molecular formula (isomers)
  • Isomerism is a defining property of carbon compounds

Organic Compounds Characteristics

  • Most organic compounds are not flammable
  • Most organic compounds are soluble in water

Inorganic Compound Properties

  • Inorganic compounds have high melting points
  • Inorganic compounds tend to be denser than water
  • Inorganic compounds include ionic and covalent bonds

Organic vs. Inorganic Compound Distinctions

  • Organic compounds generally have lower melting points compared to inorganic compounds
  • Organic compounds often showcase differences in molecular arrangement (isomers), while inorganic compounds tend not to display such differences
  • Organic compounds are primarily held together by covalent bonds; inorganic compounds often have ionic bonds in addition to covalent bonds
  • Organic compounds are usually soluble in water; inorganic compounds also dissolve in water but there are exceptions

Physical Properties of Organic Compounds

  • Boiling points are related to molecular weights; higher molecular weight often corresponds to a higher boiling point
  • Table of some organic compounds with molecular weights and boiling points can be used for reference to determine the boiling point of a specific compound
