P-methoxyphenol and acidityExplain why p-nitrophenol is a stronger acid than phenol itself. Would p-methoxyphenol be a stronger or weaker acid than phenol?
Nitrogen dioxide (NO2) cannot be obtained in a pure form in the gas phase because it exists as a mixture of NO2 and N2O4. At 25°C and 0.98 atm, the density of this gas mixture is 2.7 g/L.
