Organic Chemistry

The branch of chemistry that studies carbon-containing compounds, including hydrocarbons, alcohols, and many other molecules essential to life.

Vital Force Theory

The belief that organic compounds could only be produced by living organisms, not in laboratories.

Lavoisier

A French chemist who helped to classify compounds based on their composition, leading to the categories of organic and inorganic.

Organic Compounds contain Carbon

Lavoisier's findings showed that compounds of plant and animal origin, like sugars and fats, primarily consist of carbon.

Study Notes

Study of Carbon Compounds

  • Organic chemistry is the branch of chemistry that deals with the study of covalently bonded compounds of carbon.

Beliefs about Organic Compounds

  • In the 18th century, it was believed that organic compounds could not be synthesized in the laboratory and could only be obtained from living organisms.

Classification of Compounds

  • The scientist who reclassified compounds into organic and inorganic categories was Antoine Laurent Lavoisier.

Lavoisier's Contributions

  • Lavoisier showed that organic compounds were composed of carbon, hydrogen, and oxygen, and could be converted into inorganic compounds by chemical reactions.
  • He classified as organic compounds those that were derived from living organisms, such as sugars, fats, and proteins.
