Questions and Answers

What defines a molecule as a free radical?

  • Containing no electrons in its outer shell
  • Possessing one or more unpaired electrons in its outer shell (correct)
  • Having a complete set of paired electrons in its outer shell
  • Having a completely filled outer shell of electrons
  • How are free radicals formed?

  • By gaining an extra electron from the environment
  • Through the sharing of electrons with other molecules
  • By losing an electron to form a stable configuration
  • Via the breakage of a chemical bond such that each fragment keeps one electron (correct)
  • In what way can redox reactions contribute to the formation of free radicals?

  • By removing unpaired electrons from molecules
  • By transferring electrons between molecules, leading to the generation of free radicals (correct)
  • By stabilizing free radicals and preventing their formation
  • By neutralizing the reactivity of free radicals
  • Free radicals are always formed from molecules via the cleavage of a radical to give another radical.
