v.2. Exploring Homologous Series: Patterns and Variations in Organic Compounds 

Meaning

  • Homologous series constitutes organic compounds with the same general formula, and similar chemical characteristics but different physical properties. 
    • The adjacent members differ in their molecular formula by −CH2. 

Example

  • Methane, ethane, propane, butane, etc. are all part of the alkane homologous series.
    • The general formula of this series is CnH2n+2.
    • Methane (CH4), Ethane (CH3CH3), Propane (CH3CH2CH3), Butane (CH3CH2CH2CH3).
  • It can be noticed that there is a difference of −CH2 units between each successive compound.

Formation of coal and petroleum

  • Coal and petroleum have been formed from biomass which has been subjected to various biological and geological processes. Coal is the remains of trees, ferns, and other plants that lived millions of years ago.
  • These were crushed into the earth, perhaps by earthquakes or volcanic eruptions. They were pressed down by layers of earth and rock. They slowly decayed into coal.
  • Oil and gas are the remains of millions of tiny plants and animals that lived in the sea. When they died, their bodies sank to the sea bed and were covered by silt. Bacteria attacked the dead remains, turning them into oil and gas under the high pressures they were being subjected to.
  • Meanwhile, the silt was slowly compressed into rock. The oil and gas seeped into the porous parts of the rock, and got trapped like water in a sponge.
