`(CH_(3))_(3)C-OCH_(3)` on reaction with HI gives `(CH_(3))_(3)C-I and CH_(3)-OH` as the main products and not `(CH_(3))_(3)C-OH and CH_(3)-I`. Explain.

Text Solution

AI Generated Solution

To understand why the reaction of the ether `(CH₃)₃C-OCH₃` with HI yields `(CH₃)₃C-I` and `CH₃OH` instead of `(CH₃)₃C-OH` and `CH₃-I`, we can break down the reaction mechanism and the stability of the intermediates involved. ### Step-by-Step Solution: 1. **Identify the Ether Structure**: The given ether is `(CH₃)₃C-OCH₃`, which consists of a tert-butyl group `(CH₃)₃C-` and a methyl group `-OCH₃`. 2. **Reaction with HI**: ...
