IUPAC

Why it matters

This objective helps connect Nomenclature and formulae to exam-style questions, flashcards, and revision notes for Introduction to organic chemistry.

Quick student answer

Which of the following is the correct IUPAC name for the compound with the formula C5H12?

Direct answer

pentane

Key terms

  • Alkane: A saturated hydrocarbon with the general formula CnH2n+2, containing only single bonds.
  • Functional group: A specific group of atoms within a molecule that is responsible for the characteristic chemical reactions of that molecule.

Common trap

Incorrect naming of branched alkanes: Always start numbering from the end closest to the functional group to ensure the lowest possible numbers.
