Introduction to Organic Chemistry

Organic compounds all contain carbon.
Carbon compounds are numerous, exceeding 3 million.
Carbon can form long chains with itself. This is called catenation.

Classification of Organic Compounds

Hydrocarbons are organic compounds containing only carbon and hydrogen.
Saturated hydrocarbons contain carbons with their valence satisfied by single sigma bonds.
- Methane is an example.
Unsaturated hydrocarbons contain carbons with valence unsatisfied and involve double or triple bonds between carbons.
- Ethene and Ethyne are examples.

Further Classification of Hydrocarbons

Open chain or acyclic: These have linear structures.
- Alkanes, Alkenes, and Alkynes are examples.
Closed chain or cyclic: These have a carbocyclic ring structure.
- Alicyclic hydrocarbons include Cycloalkanes, Cycloalkenes, and Cycloalkynes.
- Aromatic hydrocarbons contain a six-membered ring with three conjugated double bonds.
  - Benzene and Phenol are examples.

Heterocyclic Compounds

Cyclic compounds that contain atoms other than carbon in the ring, such as nitrogen or sulfur, are heterocyclic.
- Furan, Pyrrole, and Pyridine are examples.

Polynuclear or Polyaromatic Hydrocarbons

These compounds contain more than one aromatic ring, either fused or in separate structures.
- Biphenyl (isolated) and Naphthalene (fused) are examples.

Structure of Atom

Atoms consist of a nucleus surrounded by electrons.
The nucleus contains protons and neutrons.
Protons and neutrons have similar masses.
Protons have a positive charge.
Neutrons have no charge.
Electrons have a negative charge and surround the nucleus in specific energy levels or orbitals.
