Questions and Answers

What is a functional group in organic chemistry?

  • A group of atoms within a molecule that has different chemical properties
  • A molecule that undergoes unique chemical reactions
  • A group of atoms within a molecule that has similar chemical properties (correct)
  • A molecule that has similar chemical properties to other molecules
  • What is the purpose of using the abbreviation R in molecular structures?

  • To denote a radioactive element in the compound
  • To represent the 'Rest of the molecule' (correct)
  • To indicate a reactive group in the compound
  • To symbolize the main functional group in the molecule
  • Why do molecules with similar functional groups tend to undergo similar reactions?

  • Because they are unreactive
  • Because they have different chemical properties
  • Because they are radioactive
  • Because they have the same chemical properties (correct)
