Questions and Answers

What is the main difference between structural and stereoisomerism?

  • Structural isomerism involves differing bonds between atoms, while stereoisomerism involves the same bonds but different atom positions (correct)
  • Structural isomerism involves different spatial arrangements of atoms, while stereoisomerism involves differing bonds between atoms
  • Structural isomerism involves different numbers of atoms, while stereoisomerism involves different spatial arrangements of atoms
  • Structural isomerism involves the same bonds but different atom positions, while stereoisomerism involves differing bonds between atoms

    • What does the term 'isomer' refer to in chemistry?
