Summary

In this episode, we delve into three common types of isomers that you are likely to encounter on the MCAT: structural isomers, geometric isomers, and stereoisomers. We start by defining each type of isomer, providing clear and concise explanations to ensure a solid understanding. Next, we present common examples of each isomer type to illustrate their unique characteristics. Finally, we discuss real-world applications and scenarios where these isomers are relevant, particularly in the context of the MCAT. This material will appear in the Physical Chemistry section of the MCAT and may also be found in the Biochemistry section.

0:00.0	Welcome to MCAT Basics, your ultimate guide to the essential topics you need to master for the MCAT,
0:07.0	brought to you by the physicians at Med School Coach.
0:10.0	Every week, Sam Smith breaks down high-yield MCAT topics, ensuring you're primed for success on test day.
0:16.0	Join Sam as we explore the most crucial subjects outlined by the AAMC, pulled from official
0:21.7	practice materials and third-party resources.
0:24.3	Get ready to elevate your MCAT game with topics tailored to maximize your score potential.
0:29.8	Hello, I'm Sam Smith.
0:32.5	The goal of this podcast is to cover the highest yield topics on the MCAT and provide you with some insight
0:38.8	into the questions that the MCAT really likes to ask. This podcast covers the three most common
0:44.7	types of isomers that you'll see on the MCAT. That's going to be structural isomers, stereo isomers,
0:50.1	and geometric isomers, which geometric isomers are technically stereo isomers as well,
0:56.1	but they're important, so I'm breaking them off and talking about them on their own.
0:59.7	And with each of these different types of isomers, I'll first give you a definition,
1:03.8	talk about a common example, and then I'll talk about some of the major applications
1:08.4	that you're most likely to see on the MCAT, like for instance,
1:11.6	how geometric isomers are related to elimination reactions. And this material is going to show up on one
1:17.5	of the four subsections of the MCAT, which is going to be the FIS chem section, although you
1:23.1	might see a little bit maybe in biochem. Anyways, thanks for listening to this podcast, and I hope that it helps in your studies.
1:29.4	I'm going to talk about three different kinds of isomers.
1:32.3	I'm going to start here with structural isomers.
1:35.3	And structural isomers are also called constitutional isomers,
1:38.6	and they are molecules which have the same molecular formula,
