The correct order of the rate of the reaction for the following reaction with respect to nucleophiles is: textCH_3textBr + textNu^ominus longrightarrow textCH_3textNu + textBr^ominus (1) textPhO^- > ^-textOH > textCH_3textCOO^- > textClO_4^- (2) textClO_4^- > textCH_3textCOO^- > ^-textOH > textPhO^- (3) textCH_3textCOO^- > textPhO^- > ^-textOH > textClO_4^- (4) ^-textOH > textPhO^- > textCH_3textCOO^- > textClO_4^-

Solution & Explanation

### Core Logic Nucleophilicity generally parallels basicity among related species (when comparing oxygen-centered nucleophiles in similar environments). Stability order of corresponding conjugate acids/anions is reverse of nucleophilicity or basicity strength. Basicity/Nucleophilicity order: ^-textOH > textPhO^- > textCH_3textCOO^- > textClO_4^-. ### Step 1: Final Conclusion Thus, option (4) represents the correct nucleophilicity order. ### Pattern Recognition Sees: Nucleophilic substitution rate and nucleophilicity order. Trap: Confusing leaving group ability with nucleophile strength. ### Chapter Mix Class 11 Chemistry: Organic Chemistry - Some Basic Principles and Techniques
