Why is benzyl alcohol a weak acid?
We know that the alcohols as well as the phenol are acidic in nature but they both are weak acids. The alcohols are less acidic than phenols so it is very difficult to quickly detach the H ion because the formed phenoxide ion is balanced to certain degree. This is the negative charge around the ring on the oxygen atom.
Are benzylic alcohols acidic?
Benzyl alcohol has moderate solubility in water (4 g/100 mL) and is miscible in alcohols and diethyl ether. The anion produced by deprotonation of the alcohol group is known as benzylate or benzyloxide….Benzyl alcohol.

m-chlorophenol
Finally we can conclude that m-chlorophenol is most acidic amongst them all. Hence, M-chlorophenol is most acidic.
Which of these is most acidic?
Presence of electron withdrawing group increases the acidic strength. So, m-chlorophenol is most acidic among all the given compounds. The correct option is (d).
Which of the is most acidic?
Solution : 2, 4, 6-trinitrophenol is the most acidic since it has three electron withdrawing `-NO_(2)` groups present. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
Which of the following is most acidic benzyl?
Finally we can conclude that m-chlorophenol is most acidic amongst them all. Hence, M-chlorophenol is most acidic.
Which compound has more pKa value?
Now higher the acidity, lighter is the value of Ka and lower is the value of pKa. Hence, benzoic acid has a higher pKa value among the four.
Which is more acidic benzyl alcohol?
So phenol is more acidic than benzyl alcohol and cyclohexanol.
