1. Define curly arrows

  • to show the movement of an electron pair in only the breaking down of a covalent bond
  • to show the movement of a single electron in the breaking down of or formation of a covalent bond
  • show the movement of an electron pair in the breaking down or formation of a new covalent bond
  • used in equations to show the products once the reaction has taken place
