The definition of a Lewis acid and base is: Acid is any substance that can accept a pair of nonbonding electrons, while that a Base is a species that contains a nonbonding pair of electrons, and in the reaction in the question:
SO3 + H2O -> H2SO3 + 2 OH-
We have SO3 as the conjugate base of the acid H2SO3 and H2O is acting as an acid in this occasion, therefore the answer is Acid
Answer:
Nucleophilic reaction
and
Explanation:
A nucleophilic reaction is a type of reaction that involves attack of a specie having a negative charge or a lone pair of electrons on a positive center. This negatively charged specie or specie having a lone pair of electrons is called a nucleophile.
An SN2 reaction is a bimolecular, concerted nucleophilic reaction that leads to inversion of configuration at the carbon center. The leaving group is the group that departs from the frontside of the molecule as the nucleophile attacks from the backside.
