The reaction of methanol and ethanol are based on their pKa values in the reaction. Fist consider the reaction of methanol with water along with their pKa values. CHX3OHpKa=15.5 +NaOH−→CHX3OX−NaX+ + HX2OpKa=15.74. Now you can see that pKa value of water is a bit higher than that of methanol so the water will react with …
