Questions & Step-by-Step Solutions

Which of the following compounds is an example of a Lewis acid?
  • Step 1: Understand what a Lewis acid is. A Lewis acid is a substance that can accept an electron pair from another substance.
  • Step 2: Look at the compound BF3 (Boron Trifluoride).
  • Step 3: Check the electron configuration of Boron in BF3. Boron has only 3 electrons in its outer shell, which means it has an incomplete octet.
  • Step 4: Since BF3 has an incomplete octet, it can accept an electron pair from another molecule.
  • Step 5: Conclude that BF3 is a Lewis acid because it can accept an electron pair.
