Consider the pair of reactions below to answer the following questions.****First set:**a. \( \text{CH}_3\text{CH}_2\text{CH}_2\text{Br} \xrightarrow{\text{ }^{-}\text{OH, } \text{H}_2\text{O}} \text{CH}_3\text{CH}_2\text{CH}_2\text{OH } + \text{ } \text{Br}^{-} \)or b. \( \text{CH}_3\text{CH}_2\text{CH}_2\text{Br} \xrightarrow{\text{ }^{-}\text{SH, } \text{RSH}} \text{CH}_3\text{CH}_2\text{CH}_2\text{SH } + \text{ } \text{Br}^{-} \)- Which reaction would be predicted to be faster? **Explain your answer** ________- The mechanism for these reactions is: a. \( \text{S}_\text{N}1 \) b. \( \text{S}_\text{N}2 \) c. E1 d. E2 **Explanation of Reactions:**- Both reactions involve a nucleophilic substitution where the bromine atom (\(\text{Br}^-\)) on the propane chain is replaced. In reaction (a), hydroxide (\(^{-}\text{OH}\)) acts as the nucleophile, and in reaction (b), thiolate (\(^{-}\text{SH}\)) is the nucleophile.- **Graph/Diagram Explanation:** There are no graphs or diagrams present in this text. The reactions are presented in text form as chemical equations.**Key Points to Consider:**- The nucleophiles (\(^{-}\text{OH}\) and \(^{-}\text{SH}\)) differ in nucleophilicity and basicity.- The thiolate ion is generally a stronger nucleophile than hydroxide due to its larger size and better ability to donate a pair of electrons.- The reactions are likely to proceed via the \( \text{S}_\text{N}2 \) mechanism as it involves a primary alkyl halide, and bimolecular nucleophilic substitution is common in such cases.

Better the leaving group faster the rate of E2 reaction Stronger the nucleophile faster the SN2 reaction
