**Question:**Which electrophile given below would react the fastest in a substitution reaction using NaCl in water?**Diagrams:**- **A:** Cyclohexane ring with a fluorine atom (F).- **B:** Cyclohexane ring with a bromine atom (Br).- **C:** Two-carbon chain with an iodine atom (I).- **D:** Two-carbon chain with a tosyl group (OTs).**Choices:**- ○ D- ○ C- ○ A- ○ B**Analysis:**The reactivity of electrophiles in substitution reactions depends on the leaving group's ability to leave. Generally, the order of leaving group ability is: I⁻ > Br⁻ > Cl⁻ > F⁻. Tosylate (OTs) is also a good leaving group. Therefore, compounds containing iodide or tosylate as the leaving group are expected to react faster in substitution reactions.**Conclusion:**Considering the leaving group order: I⁻ and OTs are better leaving groups. Hence, options C and D would react faster, with C possibly reacting fast due to the presence of iodide (I⁻), typically faster than tosylate in some reactions.
