Why do stronger nucleophiles favor SN2 reaction mechanism?

 

A stronger nucleophile is a highly electron rich or fully negative charge species. It has been experimentally found that the stronger nucleophile favor SN2 reaction mechanism.

They have a tendency to react with carbocation more quickly, before a leaving group would have a chance to dissociate and proceed through an SN1 reactionmechanism.

 

 What is magnesium carbonate?

 

Magnesium carbonate is an inorganic salt of carbonic acid with chemical formula MgCO3. Both anhydrous and hydrated forms of magnesium carbonate also exist as minerals.

The most common forms of magnesium carbonate are anhydrous salt called magnesite (MgCO3).
