The order of reactivities of methyl halides in the formation of Grignard reagent is
- A \(\mathrm{CH}_{3} \mathrm{I}>\mathrm{CH}_{3} \mathrm{Br}>\mathrm{CH}_{3} \mathrm{Cl}\)
- B \(\mathrm{CH}_{3} \mathrm{Cl}>\mathrm{CH}_{3} \mathrm{Br}>\mathrm{CH}_{3} \mathrm{I}\)
- C \(\mathrm{CH}_{3} \mathrm{Br}>\mathrm{CH}_{3} \mathrm{Cl}>\mathrm{CH}_{3} \mathrm{I}\)
- D \(\mathrm{CH}_{3} \mathrm{Br}>\mathrm{CH}_{3} \mathrm{I}>\mathrm{CH}_{3} \mathrm{Cl}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{CH}_{3} \mathrm{I}>\mathrm{CH}_{3} \mathrm{Br}>\mathrm{CH}_{3} \mathrm{Cl}\)
Step-by-step Solution
Detailed explanation
The order of reaction of methyl halides increases from fluorine to iodine due to decrease in \(C-X\) bond strength. \(\therefore\) The order of reactivities of methyl halides in formation of Grignard reagent is…
