Which among the following statements is NOT correct about SN ^2 reaction mechanism?

Options

  1. ANucleophile attacks the atom from the side opposite to halogen.
  2. BRate of reaction is dependent on the concentration of nucleophile.
  3. CBond formation and bond breaking occurs simultaneously.
  4. DSN ^2 mechanism is observed in tertiary alkyl halides.
