The Biggest Mistake Students Make With E2 Eliminations

Have you ever stared at a E2 Eliminations problem and felt like you were reading another language? You aren't alone. Let's break down exactly why this trips up so many students.

The Fatal Flaw

The vast majority of points lost on E2 Eliminations questions aren't due to bad fundamentals. They happen because of a specific blind spot: not checking for anti-periplanar geometry.

Let's look at how this breaks down in reality:

For E2 to happen in a cyclohexane ring, the leaving group and the hydrogen MUST both be in axial positions. If they are equatorial, the reaction stalls.

How to Audit Your Own Work

To stop making this mistake, you have to slow down your workflow. Create a midway checkpoint before you finalize your answer.
