(a)
Interpretation:
Based on the understanding of charge stability, it is to be determined which of the following compounds is expected to have the most similar pKa value to that of formaldehyde.
Concept introduction:
Table 6-1 refers to various compounds and their Ka and pKa values. Based on the structural similarities in compounds listed in Table 6-1 and their
(b)
Interpretation:
The pKa value for formaldehyde is to be estimated based on the concept of charge stability and the reference to Table 6.1.
Concept introduction:
pKa value represents the strength of an acid. The lower the value, the stronger the acid. Structural similarity in conjugate bases of two compounds indicates that the pKa values for the two compounds must be in the similar range. The chemical behavior of a compound is governed by the functional group it possesses.
