Acetone can be used as a solvent in the reaction between an alkyl bromide and potassium iodide to increase the amount of alkyl iodide formed. Explain. (Hint: Potassium iodide is soluble in acetone but potassium bromide is not.)

Potassium bromide precipitates out in acetone shifting the reaction to the right and increasing the amount of alkyl iodide formed.

Potassium iodide precipitates out in acetone shifting the reaction to the right and increasing the amount of alkyl iodide formed.
