Introduction to Stereochemistry Enantiomers and Chiral Molecules

October 6, 2015 By Leah4sci 34 Comments

Introduction to stereochemsitry enantiomers and chiral molecules by Leah FischChirality/Stereochemistry Video Series: Video 1
Chirality is an exciting but potentially tricky topic in organic chemistry. Why? because it's tough to visualize 2-dimensional drawings as a 3-dimensional structure. But don't be like the thousands of students struggling with this topic. My chirality series will take you through this topic step by step to ensure that you master and truly understand. Starting with video 1 below – learn exactly WHAT this is all about. From chiral carbon requirements to enantiomers as non-superimposable mirror images.

This is Video 1 in the Chirality/Stereochemistry Video Series. Click HERE for the entire series.

    I don’t see the plane of symmetry down the middle at 8:36. How is it symmetrical?

    Videos like this make me wonder if I should teach organic chenistry. Why isn’t everyone as helpful and well spoken as you? Husband seems like such a gift to impart a subject with such precision as to dissect it and remove the difficult. I love Organic Chemistry, but I love it through your mind. Thank you so much.

    Can an achiral molecule ever be non super
    imposable?

    I love your videos! They are extremely helpful. I was having trouble understanding the material in class because my professor does not explain things very well, but you explain everything clearly! It’s almost like having a personal tutor! Thank you Leah4sci!

    at 7:45 you say “two chiral molecules and they’re exaclty the same, meaning they are not mirror images” can you explain that b/c I know that chiral means asymmertrical and different subs as opposed to achiral. How can it be the exact same but not mirror images

    Great teaching video but a sequence in the video seems contradictory. When illustrating an achiral molecule with three substituents, the molecule is shown to be a mirror image and superimposable because two substituents are the same. Then later when summarizing the video states and I quote ” Notice there’s a line of symmetry going right down the center. Again a line of symmetry no matter how I turn it I can find that symmetry and that makes this molecule achiral because this molecule has a tetrahedral sp3 carbon in the center. But two of the same substituents for a total of three unique, it’s not chiral. And if it’s not chiral, IT DOESN”T HAVE A MIRROR IMAGE, its going to be superimposable, and another molecule of its kind.” This confuses me totally!!!!

      Everything that can be placed in front of a mirror has a mirror image. The question about chirality is if the molecule is superimposable ON its mirror image. Hope this makes sense

    Interesting explanation of chirality. I think practicing this modeling will be a great way to articulate. Need more videos please. Thanks
