Concept explainers
(a)
Interpretation:
The most basic site in the given species is to be determined.
Concept introduction:
Basicity of a compound depends on the
pKa value of a functional group in different compounds is similar in the absence of resonance involving the functional group.
This concept can be used to compare the basicity of different functional groups that may be present in a compound.
(b)
Interpretation:
The most basic site in the given species is to be determined.
Concept introduction:
Basicity of a compound depends on the functional groups present in it. The pKa value of a functional group determines its acidic strength as well as the strength of its conjugate base. The conjugate base formed from a weak acid is strong, and the conjugate base formed from a strong acid is a weak. The higher the pKa, weaker the acid and therefore stronger the conjugate base.
pKa value of a functional group in different compounds is similar in the absence of resonance involving the functional group.
This concept can be used to compare the basicity of different functional groups that may be present in a compound.
