MAIN CHAIN
  1. Selection of parent chain
    1. Identify the longest continuous chain of carbon atoms.
    2. If a functional group is present, select the longest chain that includes the carbon atom of the functional group.
    3. If a multiple bond (double or triple) is present, the parent chain must include the maximum number of multiple bonds.
    4. If two or more chains of equal length are possible, select the chain containing:
      1. a functional group carbon (if any)
      2. the greatest number of multiple bonds
      3. the greatest number of substituents
  2. Numbering the parent chain
    1. Number the carbon chain from the end nearest to the functional group carbon.
    2. If no functional group is present, start numbering from the end nearest to a multiple bond.
    3. If no functional group and no multiple bond are present, start from the end nearest to a substituent.
    4. If two or more substituents are present and no F.G. or multiple bond exists, apply the 'lowest set of locants' rule.
      5. Locant rule
      The sum of all the numbering of substituents.
  3. Naming substituents
    1. Identify and name all substituents attached to the parent chain.
    2. If more than one identical substituent is present, use prefixes such as di-, tri-, tetra-, etc.
    3. List substituents in alphabetical order when writing the name.
  4. Position of multiple bonds and functional groups
    1. Indicate the position of double or triple bonds by the lower-numbered carbon atom of the bond.
    2. If both double and triple bonds are present, give the lowest locant set to double bonds first (–ene before –yne in naming).
    3. Functional group gets the highest priority in numbering and naming.
  5. Writing the complete name
    1. Combine substituent names with their locants, listed in alphabetical order.
    2. Add parent chain name with suffix indicating multiple bonds (-ane, -ene, -yne).
    3. Finally, add the primary functional group suffix with its locant (if required).

CLASSIFICATION OF ORGANIC COMPOUNDS
▢ Acyclic (Open Chain) Compounds:
Also known as aliphatic compounds, these consist of straight or branched chains of carbon atoms.
❖ Saturated Compounds:
  1. Contain only single carbon-carbon (C–C) bonds.
  2. General formula: CnH2n+2 (alkanes).
  3. Carbon atoms are tetrahedral (sp3 hybridized).
  4. Highly stable and less reactive.
  5. Examples:
    1. Methane (CH4)
    2. Ethane (C2H6)
    3. Propane (C3H8).
❖ Unsaturated Compounds:
  1. Contain at least one double (C=C) or triple (C≡C) bond.
  2. General formula: CnH2n (alkenes) or CnH2n-2 (alkynes).
  3. Planar geometry around double bonds (sp2) and linear around triple bonds (sp).
  4. More reactive due to the presence of weaker π-bonds.
  5. Examples:
    1. Ethene (C2H4)
    2. Propene (C3H6)
    3. Ethyne (C2H2).
▢ Cyclic (Closed Chain) Compounds:
Compounds containing one or more closed rings of atoms in their structure.
❖ Homocyclic (Carbocyclic) Compounds:
Ring compounds containing only carbon atoms in the ring skeleton.
◉ Alicyclic Compounds:
  1. Aliphatic cyclic compounds that resemble open-chain compounds in their properties but exist in a ring form.
  2. They do not possess aromatic character.
  3. Examples:
    1. Cyclopropane (C3H6)
    2. Cyclobutane (C4H8)
    3. Cyclohexane (C6H12).
    4. Benzenehexachloride (\(C_{6}H_{6}Cl_{6}\))
      5. Image 1
      Fig.Benzenehexachloride
◉ Aromatic Compounds:
Cyclic, planar molecules with delocalized π-electron systems that follow Hückel's Rule (4n+2 π-electrons).
◈ Benzenoid Aromatic Compounds:
  1. Contain at least one benzene ring in their structure.
  2. Highly stable due to resonance energy.
  3. Examples:
    1. Benzene (C6H6)
      2. Image 1

  2. Examples:
    1. Tropolone
      2. Image 1

    2. Azulene
      3. Image 1

❖ Heterocyclic Compounds:
◉ Aromatic Heterocycles:
  1. These are cyclic, planar molecules containing one or more heteroatoms (such as N, O, or S) in the ring skeleton.
  2. They possess a conjugated system of $\pi$-electrons and follow Hückel's Rule ($4n+2$ $\pi$-electrons) to exhibit aromatic stability.
  3. Examples:
    1. Pyrrole (contains N)
