Which is more acidic o-nitrophenol or O-cresol?
O-nitrophenol is more acidic than O-cresol.
Which of the following is most acidic a phenol B m-cresol C O-cresol D o-nitrophenol?
The answer is O-nitrophenol.
Which is most acidic ethanol phenol p-cresol 4 nitro phenol?
Hence, p-nitrophenol is most acidic.
Why para nitrophenol is stronger acid than para cresol?
– CH3 group decreases the electron density on the oxygen of O-H group making p-cresol a weaker acid. B. – NO2 decreases the electron density on the oxygen of O-H group making p-nitrophenol a stronger acid.
Why is Nitrophenol more acidic than phenol?
The nitro-group is an electron-withdrawing group. The presence of this group in the ortho or para position decreases the electron density in the OH bond. As a result, it is easier to lose a proton. Hence, ortho and para nitrophenols are stronger acids than phenol.
Why is O-nitrophenol more acidic than Methylphenol?
Ortho nitrophenol is more acidic than ortho-methoxyphenol. This is because the nitro-group is an electron-withdrawing group. The presence of this group in the ortho position in ortho nitro phenol decreases the electron density in the O−H bond. As a result, it is easier to lose a proton.
Why is nitrophenol more acidic than phenol?
Which of the following is the most acidic * A p-nitrophenol B p-cresol C phenol D 2 4 6 Trinitrophenol?
Picric acid is the strongest acid due to the presence of three (NO2) group (-R and -I effect).
Which is less acidic phenol cresol propanol nitrophenol?
Therefore, acidity order wil be: p-cresol < phenol < p-nitrophenol.
Which is most acidic among phenol o-cresol?
Phenol is a stronger acid than cresol. This is because in cresol CH3 is an electron-donating group which increases the electron density on the oxygen. This means that there is an increase in the electron density in OH bond making cresol weaker acid than phenol.
Which is stronger acid phenol or cresol?
Why para nitrophenol is more acidic than phenol explain with resonance structure?
Ortho and para nitrophenols are more acidic than phenol. Draw the resonance structures of corresponding phenoxide ions. The electron withdrawing groups are more effective in increasing the acidic strength at the para-position relative to the ortho position because of greater dispersal of charge on oxygen atom.
