The rate of `SN^2` reaction depends on the effectiveness of the nucleophile in ejecting the leaving group. Nucleophilicity is the affinity for `C` atom, while basicity is the affinity for proton. In both cases, a new bond is formed. If a new bond is formed between the anion and proton, the specied acts as a base. If a new bond is formed between the anion and `C` atom, the species acts as nucleophile. Which of the following statements is wrong ?A. The nucleophilicity order in non-polar solvents (e.g., `C Cl_4, CS_2`) of the followind is : `I^(Ө) gt Br^(Ө) gt Cl^(Ө) gt F^(Ө)`.B. The nucleophilicity order in polar protic solvents (e.g., `H_2 O`) of the following is : `I^(Ө) gt Br^(Ө) gt Cl^(Ө) gt F^(Ө)`.C. The nucleophilicity order in weakly polar protic solvents (e.g., nitro benzene, acetone) of the following is : `F^(Ө) gt Cl^(Ө) gt Br^(Ө) gt I^(Ө)`.D. The nucleophilicity order in polar aprotic solvents (e.g., `DMSO, DMF`) of the following is : `F^(Ө) gt Cl^(Ө) gt Br^(Ө) gt I^(Ө)`.
