JEE Mains · Chemistry · STD 12 - 6. Haloalkanes and Haloarenes
Which one of the following reagents is not suitable for the elimination reaction ?
- A \(NaI\)
- B \(NaOEt/ EtOH\)
- C \(NaOH/H_2O\)
- D \(NaOH /H_2O-EtOH\)
Answer & Solution
Correct Answer
(A) \(NaI\)
Step-by-step Solution
Detailed explanation
Alkyl chloride or bromide undergo substitution and get converted to an alkyl iodide on treatment with a solution of sodium iodide in acetone. e.g. \(CH_3CH_2CH_2Br + NaI\) \(\xrightarrow{{acetone}}\) \(CH_3CH_2CH_2I\) + \(NaBr\) This reaction is also known as Finkelstein Reaction
