Concept explainers
(a)
Interpretation:
The arrangement of the given compounds in order of their increasing Brønsted acidity is to be stated.
Concept introduction:
The species which accepts proton from another species are termed as Brønsted base. On the other hand, the species which donates proton to another species are known as Brønsted acid. The strong conjugate acid has always a weak base.
(b)
Interpretation:
The arrangement of the compounds in order of their increasing basicity is to be stated.
Concept introduction:
Basicity is the availability of an electron pair. The electron pairs which are available can be donated easily that means basicity of that compound also increases. On moving left to right in a period, the basicity decreases as the tendency of atoms to gain electron increases. Basicity is also affected by the

- Summarize the relationship between pKa and base strength by completing the followingsentences: a. For a given base, the higher the pKa of its conjugate acid, the stronger or weaker the base. b.
