Which is more acidic P methyl phenol or p 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.

Which is more acidic p-nitrophenol or p methoxy 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 strongest acid p amino phenol P methyl phenol P nitro phenol phenol?

Phenol, p-methylphenol, m-nitrophenol and p-nitrophenol follow order of increasing acidic strength. p-Methylphenol is a weaker acid than phenol due to +Ieffect as well as +Reffect. m-Nitrophenol is a stronger acid than phenol due to -Ieffect while p-Nitrophenol is a stronger acid than phenol due to -Reffect(>-Ieffect).

What is the acidic order of O nitro phenol M nitro phenol & P nitro phenol & Why?

The acidic nature of the three nitrophenols increases in the order: meta < ortho < para. Para-nitorophenol is the most acidic among the three. The nitro group attached to a conjugated system shows strong -M effect, and this decreases the electron density more at the ortho and para positions than at the meta position.

What is the increasing order of acidic strength among the following p Methoxyphenol P methyl phenol p-nitrophenol?

Thus, the order is p-methoxphenol < p-methylphenol < p-nitrophenol.

Which is the correct order of acid strength?

The acid strength of these acids follows the order HClO4>H2SO3>H3PO4.

What is the increasing order of acidic strength among the following p methoxy?

NO2, -CN are electron withdrawing groups, tend to increase the acidic character. Thus, the order is p-methoxphenol < p-methylphenol < p-nitrophenol.

Which one of the following is most acidic phenol and Nitrophenol p-nitrophenol to methyl phenol?

While electron releasing groups (like −CH3,−OCH3 etc) destabilises the phenoxide ion by intensifying the negative charge and thus, decreases the acidity of phenol. Electron withdrawing power of nitro group is more than the chloro group. Hence, p-nitro phenol is most acidic among the given.

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

An inductive effect is an electronic effect due to the polarisation of σ bonds within a molecule or ion. 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 of the following shows the correct order of increasing acidity phenol o-nitrophenol?

Further due to posibililty of intramolecular hydrogen bonding in o-isomer, its acidic strength is slightly weasker than para-isomer. Theri acidic strength is in the order: p- nitrophenol > o-nitrophenol > m-nitrophenol > phenol.

What is the increasing order of acidity among phenol?

p-methylphenol, phenol, m-nitrophenol, p-nitrophenol.

What is the increasing order of acidic strength among the following i/p methoxy phenol?
