Question

the duulatur nucleophile after rearrangement. This is the pluu If the carbocation Is captured by the is captured by the nucleophile before rearrangement. The product distribution (ratio of products) depends on how fast the rearrangemen how fast the nucleophile attacks the carbocation. If the rearrangement occurs faste the nucleophile, then the rearranged product will predominate. However, if the nu the carbocation faster than rearrangement (if it att Gent Gif it attacks before rearrangement occurs), th arranged product will predominate. In most cases, the rearranged product predomil carbocation rearrangement is an intramolecular process, while nucleophilic attack i lar process. In general, intramolecular processes occur more rapidly than intermolecula ment takes place faster than a be pudieophil 2 us), then the dominates tack is an interme molecular prosti CONCEPTUAL CHECKPOINT 7.20 For each of the following substrates determine whether an Su 1 process is likely to involve a carbocation rearrangement -OH OH -OH OH (f) L (b) - (d) - Summary of the Sn1 Process -20-rom- and Its Energy Diagram We have seen that an Spl process has two core steps and can be accompanied by thry steps, as summarized in Mechanism 7.1.
