(a)
Interpretation:
The curved-arrow mechanism for the reversible reaction of aryl-sulfonic acid in steam is to be predicted.
Concept introduction:
Electrophilic substitution reactions are that reaction in which an electrophile replaces the atom or function group of a compound. Sulfonation is an electrophilic substitution reaction in which the hydrogen atom of an
(b)
Interpretation:
The identification of compound A, B and C in the given reaction scheme is to be predicted.
Concept introduction:
Electrophilic substitution reactions are that reaction in which an electrophile replaces the atom or function group of a compound. Sulfonation is an electrophilic substitution reaction in which the hydrogen atom of an aromatic ring is replaced by the sulfonic acid functional group.
(c)
Interpretation:
The explanation as to why compound C cannot be synthesized in one step from thiophene.
Concept introduction:
Electrophilic substitution reactions are that reaction in which an electrophile replaces the atom or function group of a compound. Nitration is an electrophilic substitution reaction in which the hydrogen atom of an aromatic ring is replaced by the nitro group.
