**Problem 7: Propose a Mechanism for the Following Reaction Favoring an SN1 Reaction**The question involves predicting a mechanism for a chemical reaction under conditions that favor an SN1 reaction. **Reactants and Products:**- **Reactant:** A cyclopentane ring attached to a carbon chain with a bromine atom (\(Br\)) as a leaving group.- **Solvent:** Water (\(H_2O\)).- **Product:** A cyclopentane ring attached to a carbon chain with a hydroxyl group (\(OH\)).**Reaction Details:**1. **Formation of Carbocation:** - The reaction begins with the departure of the bromine ion (\(Br^-\)), forming a carbocation. This step is crucial in an SN1 mechanism and involves the generation of an intermediate with a positive charge due to the loss of the leaving group.2. **Nucleophilic Attack:** - The water molecule, acting as a nucleophile, attacks the carbocation at the positively charged carbon, leading to the formation of an oxonium ion.3. **Deprotonation:** - Finally, the oxonium ion donates a proton (\(H^+\)) to the surrounding solvent, stabilizing the system and resulting in the formation of the alcohol (\(OH\)) as the final product.**Notes on SN1 Mechanism:**- An SN1 reaction involves a two-step mechanism characterized by the formation of a carbocation intermediate. - These reactions are typically favored in polar protic solvents like water, which can stabilize the carbocation and the leaving group.This illustrates a common transformation in organic chemistry where a halide group is replaced by a hydroxyl group under the influence of a polar protic solvent through an SN1 pathway.

Nucleophilic substitution reactions are those reactions in which nucleophile attacks the alkyl halide. They are of two types of nucleophilic substitution reactions that is SN1 and SN2. SN1 means unimolecular nucleophilic substitution and SN2 means bimolecular nucleophilic substitution.The above reaction is a SN1 reaction which is shown below: Mechanism: The given alkyl bromide will undergo SN1 reaction in which the formation of carbocation will take place and that carbocation will undergo 1,2-hydride shift and rearrange to form to form more stable tertiary carbocation and the nucleophile will attack that carbocation. The mechanism is shown below:
