WebVideo transcript. Here's the general reaction for a hydrohalogenation. You have an alkene, and you react that with a hydrogen halide. And the hydrogen adds to one set of your double bond, and the halogen adds to the other set of your double bond. Let's look at the mechanism for this reaction. WebS N 2 reactions at a chiral center: Another piece of evidence for the S N 2 mechanism is what happens. when an S N 2 reaction takes place at a chiral center (within a molecule). It turns out that the configuration at that center is changed; the carbon inverts (like an umbrella blowing inside out in the wind) so that an S enantiomer is converted to an R …
