The Carbon Skeleton and Functional Groups -

The Carbon Skeleton and Functional Groups

  • The skeleton or backbone of an organic molecule is made up of carbon chain.
  • The skeleton of an organic molecule determines its shape.
  • A functional group may be attached to the organic molecule.
  • A functional group can be defined as a specific combination of atoms that always react in the same way irrespective of the carbon skeleton they are attached to.
  • A functional group imparts a specific chemical identity to the carbon skeleton. For example, when -OH is attached to an organic molecule, it becomes an alcohol.
  • The functional groups determine the polarity of an organic molecule to which they are attached. 
  • It also determines the type of reaction the organic molecule would undergo.
