Vedclass · Answer

(C) The reaction of alkyl halides with sodium iodide in acetone is a Finkelstein reaction,which follows an $S_N2$ mechanism.$1.$ In Pair-$A$,$2-$Bromopropane $(2)$ reacts faster than $2-$Chloropropane $(1)$ because the bromide ion $(Br^-)$ is a better leaving group than the chloride ion $(Cl^-)$.$2.$ In Pair-$B$,$1-$Bromobutane $(3)$ reacts faster than $2-$Bromobutane $(4)$ because $1-$Bromobutane is a primary alkyl halide,which experiences less steric hindrance compared to the secondary alkyl halide $2-$Bromobutane,thus favoring the $S_N2$ pathway.Therefore,the correct compounds are $(2)$ and $(3)$.

From each of the following pairs,select the compound that will react faster with sodium iodide in acetone:
Pair-$A$: $(1) \, 2-$Chloropropane,$(2) \, 2-$Bromopropane
Pair-$B$: $(3) \, 1-$Bromobutane,$(4) \, 2-$Bromobutane
