BF 3 is an acid, according to

Options

  1. ALewis
  2. BArrhenius
  3. CBronsted and Lowery
  4. DAll of the above

Correct answer

A. Lewis

Step-by-step solution

BF 3 is a Lewis acid, as it accepts lone pair of electrons. It is not an Arrhenius acid because it does not furnish H + ion in its aqueous solution. It is also not a Bronsted Lowry acid as if does not give H + ions in any solvent.
