Which is more acidic ortho para or meta?

Of the three, ortho-chlorophenol is the most acidic with a pKa of 8.5, while meta-chlorophenol has a pKa of 9.0 and para-chlorophenol is the weakest acid with a pKa of 9.4.

What is the correct order of acidic strength I para methoxyphenol II meta methoxyphenol III ortho methoxyphenol?

p-nitro phenol is more acidic than p-methyl phenol.

Which is more acidic para methyl phenol or meta methyl phenol?

Resonance in phenol: Para-nitro phenol is most acidic among the following because the base abstracts the proton from the –OH group of phenol. Methyl phenol shows the electron donating inductive effect, hence it is least acidic among the following. So, the correct answer is “Option A”.

Is meta methoxyphenol more acidic than Phenol?

Answer: Phenol is more acidic than Methoxy phenol. When in the ortho,para-positions (relative to the -OH group of phenol), resonance tends to dominate while in the meta-position, the inductive effect is the only effect .

Which is more acidic meta 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.

Which of the following is most acidic methoxy phenol?

Out of para-methyl phenol and para-methoxy phenol, para-methyl phenol is more acidic since the methyl group has a weak +R effect whereas the methoxy group has a strong +R effect which will make the corresponding phenoxide conjugate base less stable. Given below are the resonance structures for the para-methoxy phenol.

Is phenol is more acidic than para Methylphenol?

Now , in para methyl phenoxide ion due to +I effect of methyl group , the density of electron on oxygen ion increases . So the stability of para methyl phenoxide ion is decrease than phenoxide ion . Consequently, para methyl phenol is less acidic than phenol .

Which is more acidic phenol or meta nitrophenol?

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. Effect of substituent is more when groups are attached at ortho and para positions rather than at meta position.
