Picric acid is 2,4,6-trinitro phenol, the nitro groups are electrons withdrawing groups so are responsible to make the bond weaker between oxygen and hydrogen atoms and increase the acidic strength as compare to phenol.

Difference in pH between any substances is reliant on the compounds' ionisation potential.

for acids in this case, it is because picric acid produces more Hydrogen+ ions in solution than phenol, per same number (moles) of molecules.

Which is more acidic hydrochloric acid or picric acid?

Hydrochoric acid is more acidic than Picric acid.Added: Ka(Picric acid) = 0.38, Ka(HCl) >>1


Is 1-hexanol more acidic or less acidic than phenol?

1-hexanol is an alcohol so it is a neutral compound not an acid while phenol is a strong acid.


Is water more acidic than phenol?

No. Phenol is far more acidic than water.


Is alcohol acidic or basic?

No, it isn't. It's essentially neutral. Some alcohols are weakly acidic... phenol is one of the more acidic ones, and was at one time even called "carbolic acid."


Why are phenols acidic in nature?

Phenol can act as an acid due to it's stability as phenoxide ion. By releasing H+ ion it will form stable C6H5O- ion. The groups having +I, -I , +M , -M efffects present on phenol will effect acidic nature of phenol. As +I or +M groups which are present at ortho and at para psitions will decrease the acidic character of phenol. If they are at meta position effect is less than at para or ortho positions.Similar to this -I or -M gorups are substituted on phenol they will increase the acidic nature. so, we can say that as the stability of phenoxide ion increases acidic nature of phenol also increases.Phenol can act as an acid due to it's stability as phenoxide ion.

Is c6h5oh acidic or basic?

C6H5OH is considered acidic. It is more commonly known as phenol, or carbolic acid, which is a type of organic solid known for its volatility and crystalline structure.

Which is more acidic p-chloro phenol or p-fluoro phenol?

p-chloro phenol is more acidic thisi is because in p-fluoro phenol as fluorine and carbon have identical 2p orbitals, the overlapping is perfect Hence the +r effect and -I effect cancels thus making it less acidic


Which is more acidic phenol or para-chloro phenol?

Phenol. Anisole doesn't have any acidic protons.


Why phenol more acidic than aliphatic alcohol and water?

Which is a stronger acid cresol or phenol?

Phenol is more acidic because cresol has +I effect of CH3 grup as you know acidity is reciprocal of +I effect. OR Cresol has electron donating methyl group, whih reduces its electron defficiency of the phenol group and hence acidity.


Why is phenol more soluble in aqueous NaOH than in water?

Phenol is acidic in nature. The phenolate anion is stable through resonance. Hence, an acid base reaction ensues between phenol and NaOH in water resulting in the formation of sodium phenolate, which is highly soluble in water compared to phenol.
