Substitution & Elimination Reactions

Substitution & Elimination Reactions

This webinar addresses the major reaction types tested on the MCAT. You will learn about the different types of substitution and elimination reactions, their mechanisms, and how to predict the mechanism of a given reaction based on the reaction conditions. You will also learn how to determine the correct product of a substitution or elimination reaction.

At a glance


Essential skills

  • Determine the mechanism of a reaction based on nucleophile/base strength, sterics, and solvent

  • Determine the product of a substitution or elimination reaction


Knowledge Fundamentals

  • The mechanisms for both types of substitution and elimination reactions

  • The different types of solvents


On the MCAT

  • The MCAT will rarely give you reaction mechanism, but they will usually write out the reaction

  • Consider reaction conditions when determining the correct mechanism (nucleophile or base, temperature, solvent)

  • Draw out the molecule and/or mechanism if it is not given


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
