What we have learnt

  • Organic compounds are primarily composed of carbon and can form a variety of structures due to strong covalent bonds.
  • The systematic nomenclature developed by IUPAC provides a standardized way to name and deduce the structure of organic compounds.
  • Hydrocarbons are classified into alkanes, alkenes, and alkynes, each possessing distinct properties and reactivities.
  • Functional groups impart specific characteristics to organic compounds and determine their chemical behaviors.
  • Isomerism in organic compounds can significantly alter their physical and chemical properties.

Key Concepts

-- Nomenclature
A systematic way to name organic compounds based on IUPAC rules, involving prefixes, root names, and suffixes.
-- Hydrocarbons
Organic compounds comprising only hydrogen and carbon; they are categorized into alkanes, alkenes, and alkynes.
-- Functional Groups
Specific groups of atoms within molecules that dictate the chemical reactivity and properties of those molecules.
-- Isomerism
The phenomenon of compounds having the same molecular formula but different structures or arrangements of atoms.
-- Aromaticity
A property of cyclic compounds like benzene that involves a stable arrangement of pi electrons, leading to unique chemical behavior.
