  • Effect of Hybridization on bond length and bond enthalpy. The bond length and bond strength depend upon hybridization.
  • sp-hybridised ‘C’ has 50% ‘s’ character, hence it is close to the nucleus and forms shorter and stronger bond. It is most electronegative.
  • sp2–hybridised ‘C’ has 33% ‘s’ character, hence it is lessrclose to the nucleus and forms slightly longer and less strong bonds than ‘sp’-hybridised ‘C’. It is less electronegative and bigger than ‘sp’-hybridised.
  • sp3–hybridised ‘C’ 25% ‘s’-character, hence it is least close to nucleus and forms longer and least strong bonds. It is bigger in size and less electronegative than sp2 and ‘sp’-hybridised ‘C’.
  • Conformations. In ethane, the rotation of one CH3 fragment against another in a molecule doesi affect overlap in a sigma bond. Consequently, free rotation around a-bond is permissible. The carbon-carbon a-bond rotation results in different interconvertible forms of molecules known! Conformations.

Classification of Organic Compounds:

  • Aliphatic compounds. Those compounds which are open chain compounds are called aliphatic compounds. They are also called acyclic compounds, e.g., propane, 1, 3-butadiene, butene, hexane, decane, etc.
  • Alicyclic compounds. Compounds containing closed ring of carbon atoms are called Alicylic compounds, e.g., cyclopropane, cyclobutene, cyclohexane, etc.
  • Aromatic compounds. Benzene and its derivatives are called aromatic compounds, e.g., benzene, toluene, phenol, aniline etc.
  1. Benzenoid aromatic compounds
  2. Non-benzenoid aromatic compounds

aromatic compound

  • Heterocyclic aromatic compounds

heterocyclic compound

  • Functional Group. Functional group is an atom or a group of atoms or reactive par of the compound which determines physical and chemical properties of compounds e.g., –OH, –CHO, –OR, –COOH groups etc.
