Which is more acidic m-nitrophenol or p-nitrophenol?

Which is more acidic m-nitrophenol or p-nitrophenol?

p-nitrophenol. o-nitrophenol. m-nitrophenol. Thus, ortho and para-nitrophenols are more acidic than m-nitrophenol is a little less acidic than p-nitrophenol because of intramolecular hydrogen bonding which makes the loss of a proton difficult to remove.

Which is more acidic water nitrophenol or para nitrophenol?

Nitro in ortho position can hydrogen bond with the phenolic hydroxyl group and consequently the proton is not given out easily making it less acidic than p-nitrophenol. This effect dominates all the above effects and hence p-nitrophenol is more acidic than o-nitrophenol.

Why is p-nitrophenol stronger acid than m-nitrophenol?

NO2 group at o and p position withdraws electron of o-h bond towards it by stronger M-effect while the NO2 group at m position withdraws electron of o-h bond by weaker I -effect . Thus o and p are nitrophenols are more acidic than m-nitrophenol.

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 nitrophenol so acidic?

So, the electron density in the O-H bond of p-nitrophenol decreases relative to the O-H bond of phenol. The decrease in electron density of the O-H bond of p-nitrophenol, the polarity of O-H bond is decreases and in turn make it more acidic than phenol.

Which is more acidic phenol or meta 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.

Which is more acidic ortho or para?

Ortho nitrophenol is less acidic than para nitrophenol because of the intermolecular hydrogen bonding which makes the loss of proton very difficult. So, para nitrophenol is more acidic.

Why is Orthonitrophenol less acidic than para nitrophenol?

Which is more acidic meta Methoxyphenol or 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 .

Is p-nitrophenol an acid or base?

The compound p-nitrophenol is more acidic than just plain old phenol (see structures below). Why do you think this might be? The proton on the OH group of the p-nitrophenol compound is about 1000 times more likely to dissociate than the proton on the OH group of the phenol compound.

Why is p-nitrophenol more acidic than P methyl phenol?

P-Nitrophenol is more acidic than p-methyphenol because P-Nitrophenol has electron with drawing group. Which is more effective while P-methylphenol has methoxy group.

Which of the following is most acidic p-nitrophenol?

Electron withdrawing power of nitro group is more than the chloro group. Hence, p-nitro phenol is most acidic among the given.
