The fastest reaction rate in bimolecular nucleophile reaction is given by :
Correct answer - option ( a ) Iodocyclohexane
Explanation : Bimolecular nucleophile is faster in primary alkyl halide. Among primary alkyl halide, iodo group (- I) is a strong leaving group and hence the reaction rate will be higher. Thus, iodocyclohexane have the fastest reaction rate among the given compounds.
