So, the acidity of m-chlorophenol is higher than phenol. Finally we can conclude that m-chlorophenol is most acidic amongst them all. Hence, M-chlorophenol is most acidic.
Which of the following is most acidic phenol?
Amongst the following phenols which one is most acidic ?
- A. Picric acid.
- B. 2-Nitrophenoi.
- C. 2,4-Dinitrophenol.
- D. m-Nitrophenol.
- Answer. A.
- Solution. Picric acid is the strongest acid due to the presence of thee (NO2 group (-R and -I effect).
Is benzyl alcohol most acidic?
Phenol are more acidic than aromatic alcohols such as benzyl alcohol and also more acidic than alcohols such as cyclohexanol.
Which one of the following is most acidic?
In o−nitrophenol, −NO2 is electron withdrawing group and stabilises the phenoxide ion. See the figure, Hence, It is more acidic.
Is benzyl alcohol more acidic than phenol?
Hence, m-chlorophenol is more acidic than phenol.
Which phenol is more acidic in nature?
Phenol is more acidic than aliphatic compounds containing OH group due to resonance stabilization of phenoxide ion by the aromatic ring. In this way negative charge of oxygen atom is delocalized on ortho and para carbon atoms. Due to which stability increases.
Which is more acidic phenol or cyclohexanol?
Phenol is more acidic than cyclohexanol and acyclic alcohols because the phenoxide ion is more stable than the alkoxide ion. In an alkoxide ion, such as the one derived from cyclohexanol, the negative charge is localized at the oxygen atom. … Phenols substituted with electron-donating groups are less acidic than phenol.
Which alcohol is most acidic?
Therefore, in the gas-phase, t-butanol is the most acidic alcohol, more acidic than isopropanol, followed by ethanol and methanol.
What makes an alcohol more acidic?
The key factor in determining acidity is the stability of the conjugate base. Any factor which makes the conjugate base more stable will increase the acidity of the acid.
Which is less acidic than phenol?
Water (pKa=14) is less acidic than phenol (pKa≡8). Presence of electron donating group (methyl) in o-cresol makes it less acidic than phenol.
Which acid Below is the strongest?
Answer: HFSO3 is the strongest acid.
Which one of the following is most acidic CH3OH?
Thus, CH3OH will be most acidic in nature. So, the correct answer is “Option C”.
Which one of the following is most acidic Al2O3?
Na2O, MgO, CaO are metallic oxide of s block. These maetallic oxides powerful bases, while Al2O3 is metallic oxide of p block which has comapratively more acidic character. Hence, it is the most acidic oxide among all.
Which is more reactive benzyl alcohol or phenol?
In benzyl alcohol (III), the OH group is not directly attached to the ring and is not in a position to activate it. Phenol (I) is the most reactive because phenolic group activates the ring towards electrophilic attack both at the ortho and para positions.
Which is more acidic phenol or chlorophenol?
m chloro phenol will be more acidic since -Cl attached to the phenol is electron withdrawing, making it more acidic… however if the -Cl was present in the ortho or para position, it would make it even more acidic…
Is benzyl alcohol acidic or basic?
Benzyl alcohol is an extremely weak basic (essentially neutral) compound (based on its pKa).
