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. WebIn those reactions, the use of polar protic solvents favors the S N 1 reaction mechanism, while polar aprotic solvents favor the S N 2 reaction mechanism. The S N 1 reaction works well for tertiary alkyl halide because the loss of the leaving group forms a tertiary carbocation which is the most stable form of carbocations. flight jfk to romeWebStep 1.

"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 ... " - H2s sn1 reaction
