Web20. júl 2024 · The phenol derivative picric acid has a pKa of 0.25, lower than that of trifluoroacetic acid. Use a resonance argument to explain why picric acid has such a low pKa. Consider the acidity of 4-methoxyphenol, compared to phenol. Notice that the methoxy group increases the pKa of the phenol group - it makes it less acidic. Why is this?
