This video features additional nucleophilic substitution examples showing you how to choose between SN1 and SN2 reactions. Learn how to choose the appropriate mechanism and product based on the provided starting molecule, leaving group, reacting nucleophile and solvent.   (click HERE to watch this video on YouTube) Watch Next Video: E1 Reaction Rate and Mechanism […]

Choosing Between SN1 and SN2 Reactions Part 1

SN1 SN2 E1 Series: Video 15 Knowing that your alkyl halide will undergo nucleophilic substitution is not enough. As you work through these reactions pay attention to the key factors that help you distinguish between unimolecular and bimolecular substitution reactions. This is SN1 vs SN2 video one. Additional examples in the next video (Watch on […]

SN2 Reaction vid Bimolecular Nucleophilic Substitution Part 3

SN1 SN2 E1 Series: Video 14 Bimolecular substitution is a fast reaction which requires a good leaving group. Or at least one that can be kicked out easily. However, when faced with a bad leaving group, you must first ‘bribe’ the atom turning into a more willing leaving group before proceeding with the reaction. This […]

SN2 Reaction Chirality and Mechanism of Bimolecular Substitution Part 2

SN1 SN2 E1 Series: Video 13 When starting with a chiral alkyl halide, the SN2 reaction will undergo a backside attack and thus an inversion in chirality. This video shows you a breakdown of the chiral inversion to help you understand how easily to identify chiral SN2 reaction products. (Watch on YouTube: SN2 Part 2. […]

SN2 Reaction Rate and Mechanism Bimolecular Substitution Part 1

SN1 SN2 E1 Series: Video 12 The first of 3 SN2 videos, this video gives you a detailed overview of the bimolecular nucleophilic substitution reaction, reaction rate, step by step mechanism. Pay special attention to the features that determine an SN2 reaction and the potential chirality of the final product.   (Watch on YouTube: SN2 […]

SN1 Reaction Mechanism with Hydride Shift and Carbocation Rearrangement Part 3

SN1 SN2 E1 Series: Video 11 In this final SN1 video you’ll see tricky examples involving less substituted carbocation intermediates followed by carbocation rearrangements and hydride shifts. When working through these reactions pay special attention to the patterns that help determine the SN1 mechanism over a potential SN2 or E2 (Watch on YouTube: SN1 Part […]

SN1 Reaction Mechanism Examples of Unimolecular Substitution Part 2
