Which is more acidic alcohol phenol or water?

The presence of the electron-withdrawing group increases the acidity of phenol by sustaining the resulting phenoxide ion and on the other side presence of the electron releasing group decreases the acidity of phenol by destabilizing the phenoxide ion.

Which of the following is the strongest acid ethanol phenol and ethanol benzoic acid?

The correct order of increasing acidic strength is Ethanol < Phenol < Acetic acid < Chloroacetic acid. Phenol is more acidic than ethanol because in phenol, the phenoxide ion obtained on deprotonation is stabilized by resonance.

Which of the following is weakest acid phenol?

(2) Hydrocyanic acid (K = 4.9 x 10-10) (4) Benzoic acid (K = 6.5 x 10-5) Greater the K value means Higher Acidic strength and smaller the K value means weaker acidic strength. As Phenol has least K value hence it is weakest acid.

Which is the stronger acid benzoic acid or phenol?

However the conjugate base of phenol, a phenoxide ion has non- equivalent resonance structure in which the negative charge is at the less electronegative carbon atom. Thus the benzoate ion is more stable than phenoxide ion. Hence, benzoic acid is a stronger acid than phenol.

Why phenol is stronger acid than ethyl alcohol?

Phenol is more acidic than that of ethanol because phenoxide ion is stabilized through delocalisation. When phenol loses an H+ ion, the ion formed is known as phenoxide ion. Its chemical formula is C6H5−O−. The negative charge formed as a result of losing an H+ ion is not localised in phenol.

Which of the following is strongest acid phenol?

Therefore, nitrophenol (a) is the strongest acid.

Which of the following acids are stronger than ethyl alcohol?

(a) Acetic acid is a stronger acid than ethyl alcohol because the acetate ion formed by ionisation is stabilized by resonance while the ethoxide ion has no resonance.

Which is the following is weakest acid?

HF is the weakest acid as it does not give proton easily.

Which is more acidic benzoic acid or methylbenzoic acid?

Benzoic acid is more acidic than 2- methyl benzoic acid because CH3 has +I effect and hyperconjugative effect that destabilizes the carboxylate ion.

Which is more acidic formic acid or phenol?

Formic acid is more acidic than phenol.
