(a)
Interpretation:
The steps of the given reaction are to be classified as Lewis acid-base association reaction, Lewis acid-base association reaction, electron-pair displacement reaction, a Brønsted acid-base reaction.
Concept introduction:
Lewis acid-base association reactions are those reaction in which a compound dissociates to form a Lewis acid and a Lewis base as a product. Brønsted acid-base reactions are those reactions in which electron pair displacement takes place and electrophilic center is a proton. Lewis acid-base association reactions are those reaction in which a Lewis acid combines with Lewis base to form a product.
(b)
Interpretation:
The conjugate acid-base pair formed in the Brønsted acid-base reaction is to be indicated.
Concept introduction:
Brønsted acid-base reactions are those reactions in which electron pair displacement takes place and electrophilic center is a proton. The species which accepts proton are known as Brønsted base. On the other hand, the species which donates proton from another species are termed as Brønsted acid.
(c)
Interpretation:
Each atom of the species present in the mechanism is to be classified as a nucleophile, nucleophilic center, electrophile, electrophilic center, leaving group, Brønsted base, Brønsted acid.
Concept introduction:
The species which donates electron pair is known as Lewis base. On the other hand, the species which accepts electron pair from another species is known as Lewis acid. Lewis acid-base association reactions are those reaction in which a Lewis acid combines with Lewis base to form a product.
(d)
Interpretation:
The curved arrow notation of each step is to be drawn.
Concept introduction:
The curved-arrow notation is used to show the transfer of electrons from one atom to another. The curved arrow has two barbs (head and tail) which represent the direction of electron flow.
