Is methanol a weak acid
WitrynaAt pH 3.0, as percent methanol increases, the retention times of both phenol and benzoic acid decrease significantly. Because both solutes are polar, increasing mobile-phase polarity causes both to be retained less tightly. Witryna23 sty 2024 · Therefore, methanol is more acidic than t-butanol because the smaller methoxide ion has a shorter radius of solvation, leading to a larger solvation energy, which overcomes the stabilization that results from polarization of the charge.
Is methanol a weak acid
Did you know?
WitrynaGenerally, the stronger the acid, the lower the pK a. The pK a value for methanol is 16, for water is 15.7 (know these values). Since the pK a value of water is less than methanol, the dissociation of methanol is harder than water and water is a stronger acid than methanol. Remember that the pK a and pK w for water are not the same. K w = … Witryna13 sie 2024 · Give two reactions that show the acidic nature of phenol.
