Define Allotrophy

When an element possess 2 or more different forms in the same state, they are called allotropes and the phenomenon is known as allotropy. Diamond and graphite are the 2 allotropes of carbon.

Key Points

Key Points: Straight chains, Branched chains, and Rings of Carbon atoms
  • Carbon compounds can have straight, branched, or ring chains of carbon atoms.
  • Isomers have the same formula but different structures (e.g., butane).
  • Crude oil is a mix of hydrocarbons; fuels like LPG and petrol are separated by fractional distillation.
  • Saturated hydrocarbons have single bonds, while unsaturated ones have double or triple bonds.
  • Aromatic compounds, such as benzene, have rings with alternating double bonds.
