Is bromophenol more acidic than phenol?

O-cresol, m- cresol, p-cresol, o- fluorophenol, o- chlorophenol, o-bromophenol. Given halophenols are more acidic than phenol.

Which is more acidic nitrophenol or cresol?

Whereas due to + I effect of — CH3 group, electron density increases in the O – H bond of o-cresol. Thus, O – H bond of o-nitrophenol is weaker than O – H bond of o-cresol and o-nitrophenol is more acidic than o-cresol.

Which is more acidic M nitrophenol or phenol?

Whereas electron donating groups decrease acidic strength of phenol by destabilizing the anion. Groups like NO₂,CN,CHO,COOH etc. withdraw electrons from benzene ring and and stabilize the anion and hence increases the acidic strength. Hence nitrophenol is more acidic than phenol.

Why is meta cresol more acidic than Ortho cresol?

m-cresol is the more acidic than p-cresol because in ortho and para isomers, hyperconjugative effects of -CH3 group lead to an increase in electron density on the oxygen atom.

Which is more acidic phenol or m chlorophenol?

Due to electron withdrawing nature of –Cl group or halogen group it is easier to remove hydrogen from m-chlorophenol as compared to phenol. So, the acidity of m-chlorophenol is higher than phenol. Hence, M-chlorophenol is most acidic.

Which of the following is most acidic among phenol o-cresol p cresol m-cresol?

The o-cresol is the least acidic as the electron-donating group is very near to the anion which will be formed after donating hydrogen which destabilizes it. Therefore, the acidity order will be m-cresol > p-cresol > o-cresol that shows option C as the correct choice.

Which of the following is more acidic o-cresol?

o-nitrophenol
In other words, o-cresols have less tendency to form stable phenoxide ion by releasing a proton. Hence, o-nitrophenol is more acidic than o-cresol.

Which one is more acidic p-nitrophenol or p-cresol?

In p-nitrophenol, nitro group shows −Meffect which stabilises the conjugate anion hence, it will be most acidic. In p-cresol, methyl group shows +Heffect which destabilises the conjugate anion hence, it will be least acidic.

How do you arrange nitrophenol in order of decreasing acidic strength?

Arrange the following in order of decreasing acidic strength. p- nitrophenol (I), p-cresol (II), m-cresol (III), phenol (IV) : When an electron withdrawing nitro group is present in para position to −OH group, the acidity is enhanced due to stabilization of phenoxide ion.

Why is O-nitrophenol a stronger acid than phenol?

Phenol, o-nitrophenol, o-cresol Due to the -I-and -R-effect of o-nitrophenol, it is a stronger acid than phenol thus making the release of H+ ion from O — H bond easier. —I- and —R-effect increases the acidic strength by increasing the polarity of —OH bond.

What is the Order of acidity of P-methylphenol?

p-methylphenol, phenol, m-nitrophenol, p-nitrophenol -I group increases acidity of the compound whereas +I group reduces acidity. At m-position with respect to -OH, the nitro group increases the acidity lesser than that of at Ortho and Para-positions. The correct order of acidity is shown above.
