WebVideo transcript. - [Lecturer] Since the SN1 mechanism involves the formation of a carbocation a rearrangement is possible. So let's look at this SN1 reaction. On the left is our alkyl halide, ethanol is our solvent and on the right is our product. The first step should be loss of a leaving group. WebThe reaction is like SN1. It is NOT SN1 but it is carbocationic character driven. Think of it like this, The strong nucleophile will attack vigorously and will not be selective ie. it will attack the carbon which is easily available to it, the one less hindered. Whereas the weak nucleophile which won't be vigorous would be selective and would ...

WebNo, 2° substrates can react via SN1 or SN2, depending on the conditions. We have two competing processes. If the nucleophile attacks faster than the leaving group spontaneously leaves, the reaction is SN2. If the leaving group leaves before the nucleophile can successfully attack, we have SN1.

"WebStep 1. The carbon-bromine bond is a polar covalent bond. The cleavage of this bond allows the removal of the leaving group (bromide ion). When the bromide ion leaves the tertiary butyl bromide, a carbocation intermediate is formed. As mentioned earlier, this is the rate-determining step of the S N 1 mechanism. " - H2s sn1 reaction
