Statement I : Reaction of 2-bromo-3-mehylbutane with ethanol gives 2-ethoxy-3-methylbutane
Statement II : 1, 4-Hydride shift occurs and forms the unexpected product
Statement II : 1, 4-Hydride shift occurs and forms the unexpected product
View answer and explanation
Correct option: D
Statement II is correct but statement I is incorrect
Option D is correct. Statement I is incorrect because the reaction likely proceeds via an SN1 mechanism with carbocation rearrangement, leading to a different product. Statement II is correct because a hydride shift can occur.
