The methyl sulfate and p‐toluenesulfonate ions are good leaving groups because they are weak bases and are stabilized by resonance.
Explanation:
Good leaving groups are weak bases. They don't want to share their electrons.
For example, the
These ions are stabilized by resonance, and that also makes them good leaving groups.
