Lewis acids and bases are very important in how chemical reactions work. They help us understand how electrons interact. Let’s break this down a bit:

1. What Are They?

   • Lewis Acids: These are substances that can accept electrons. Examples include compounds like BF₃ and AlCl₃.
   • Lewis Bases: These substances donate electrons. Common examples are NH₃ (ammonia) and H₂O (water).

2. How They Work Together:

   • Lewis acids make other substances more likely to react by pulling in electrons. This can speed up reactions by up to 100 times!
   • Lewis bases help to stabilize the reaction’s half-way point, which is called the transition state. This helps in getting more good products from the reaction.

3. Where They're Used:

   • You can find Lewis acids and bases in many chemical processes. About 70% of organic reactions rely on these pairs to work.

When we understand how Lewis acids and bases interact, we can better predict how reactions will happen and what the final results will be.
