![SN2 Reaction
lodide ion is an effective nucleophile in S2 displacements. In acetone solution, other
alkyl halides can be converted to alkyl iodides:
CH;CH2
CH,CH3
I-C
H;C H
acetone
X-
Na I-
H CH3
Na X
X-Clor Br
TR)
Although you might expect such a reaction to be reversible, it can be made to proceed
in the forward direction by using anhydrous acetone as the solvent because sodium
iodide is soluble in this solvent, but sodium chloride and sodium bromide are not. We
can detect whether a reaction has occurred by the formation of a precipitate of
sodium chloride or bromide.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Facdebdf9-7d3d-4825-b175-257d67952467%2F890d38bd-06ea-4794-bbb5-a70b7c8b5937%2Fc4u3l7_processed.jpeg&w=3840&q=75)
