What to Focus On
- Berzelius proposed the vital force theory.
- Wohler synthesised urea from ammonium cyanate in 1828.
- Kolbe synthesised acetic acid in 1845.
- Carbon forms four covalent bonds.
- sp3, sp2, and sp hybridisation explain methane, ethene, and ethyne.
- sp orbitals form shorter and stronger bonds than sp3 orbitals.
- Pi bonds form by sideways overlap of p orbitals.
- Rotation about C=C is restricted.
- Pi electrons lie above and below the bond plane.
Common Mistakes to Avoid
Wohler proposed the vital force theory and later supported it with urea synthesis.
Carbocations are sp3 hybridised and carbanions are planar.
Heterolytic cleavage always gives free radicals, and homolytic cleavage always gives ions.
Memory Tips

Classification of organic compounds
Acyclic compounds are aliphatic compounds
Alicyclic compounds are ring-shaped but aliphatic in nature
