Assertion : Alkyl iodide can be prepared by treating alkyl chloride/br

1.	Assertion : Alkyl iodide can be prepared by treating alkyl chloride/bromide with NaIin acetone.Reason : NaCl/NaBr are soluble in acetone while NaIis not.(a) Both A and R are true and R is the correct explanation of A(b) Both A and R are true but R is not correct explanation of A(c) A is true but R is false(d) A and R are false
Answer» The correct option is(c) A is true but R is false. Explanation: This is Finkelstein reaction which involves the conversion of an alkyl chloride/bromide to an alkyl iodide by the addition of sodium iodide in acetone. Because sodiumiodide is soluble in acetone and NaCl and NaBr are not, the equilibrium is shifted by the precipitation of insoluble salt. The equilibrium position of the reaction depends on the nucleophilicity of the anion, whether a good leaving group is present and whether one anion is better stabilised than the other in a given solvent.

Answer»

The correct option is(c) A is true but R is false.

Explanation:

This is Finkelstein reaction which involves the conversion of an alkyl chloride/bromide to an alkyl iodide by the addition of sodium iodide in acetone. Because sodiumiodide is soluble in acetone and NaCl and NaBr are not, the equilibrium is shifted by the precipitation of insoluble salt.

The equilibrium position of the reaction depends on the nucleophilicity of the anion, whether a good leaving group is present and whether one anion is better stabilised than the other in a given solvent.
