Concept explainers

Organic Chemistry deals mostly with carbon and hydrogens, also called hydrocarbons, but those groups which replace hydrogen and bonds with carbon to give a characteristic nature, unique of their own, to the hydrocarbon they are attached to, are called fu…

Characteristics Of Functional Groups

In organic chemistry, we encounter a number of special substituent groups which are attached to the hydrocarbon backbone. These groups impart certain characteristics to the molecule of which it is a part of and thus, become the highlight of that particul…

IUPAC Nomenclature

In Chemistry, IUPAC stands for International Union of Pure and Applied Chemistry which suggested a systematic naming approach for the organic and inorganic compounds, as in the beginning stage of nomenclature one single chemical compound was named in man…

PRACTICE PROBLEM

If we examine Table 21.1, we see that phenols having electron-withdrawing groups (Cl─ or O2N─) attached to the benzene ring are more acidic than phenol itself. Account for this trend on the basis of resonance and inductive effects. Your answer should also explain the large acid-strengthening effect of nitro groups, an effect that makes 2,4,6-trinitrophenol (also called picric acid) so exceptionally acidic (pKa = 0.38) that it is more acidic than acetic acid (pKa = 4.76).
