Chemistry - Acids and Bases - Lewis acid-base theory - Lewis Acid-Base Step by Step
4-step explanation. Step 1: 'THE KEY IDEA: Lewis acids have an EMPTY orbital that can accept an electron pair. Lewis bases have a LONE PAIR they can donate. When base donates lone pair to acid → coordinate (dative) bond forms.' Step 2: 'COMMON LEWIS ACIDS: BF₃ (empty p orbital on B), AlCl₃ (expandab
