Study Notes

  • Organic chemistry includes medicine, the environment, chemical biology, energy, natural products and asymmetric catalysis.

Question

  • Butterflies, birds, giraffes, humans and plants are all made up of carbon-based compounds.

What is Organic Chemistry?

  • A branch of chemistry deals with molecules with carbon and hydrogen.
  • These compounds are called hydrocarbons.

Organic Compounds

  • Carbon-based molecular compounds do not include CO(g), CO2(g), and HCN(g)
  • Organic compounds make up living organisms
  • These are widely used as natural and synthetic polymers.

Types of Hydrocarbons

  • Hydrocarbons are categorised as saturated, unsaturated, and aromatic.
  • Saturated hydrocarbons are alkanes.
  • Unsaturated hydrocarbons are alkenes and alkynes.
  • Aromatic hydrocarbons are arenes.
  • Saturated and unsaturated hydrocarbons are also called aliphatics.

Types of Organic Compounds

  • Organic compounds are classified according to functional group.
  • Types of organic compounds include: alkane, alkene, alkyne, haloalkane, alcohol, ether, ketone, aldehyde, carboxylic acid, amine, amide, and amino acid.
