Text Solution

Verified by Experts

The correct Answer is:
A
In `CH_(3)OC_(2)H_(5)`. Attack of `I^(-)` ion occurs at `CH_(3)` group giving `CH_(3)I and C_(2)H_(5)OH.` However, in `(CH_(3))_(3)COCH_(3),` the reaction proceeds by `S_(N^(1))` mechanism and `I^(-)` ion attack more stble `(CH_(3))_(3)C^(+)` ion giving `(CH_(3))_(3)CI and CH_(3)OH`.
