Options

  1. AThe contributing structures must have the same number of unpaired electrons.
  2. BThe contributing structures should have similar energies.
  3. CThe contributing structures should be so written that unlike charges reside on atoms that are far apart.
  4. DThe positive charge should be present on the electropositive element and the negative charge on the electroneg

Correct answer

C. The contributing structures should be so written that unlike charges reside on atoms that are far apart.
