WebThe acidic character of alcohols is due to the electronegative oxygen atom which withdraws the electrons of the O-H bond towards itself. As a result, the O-H bond becomes weak and hence a proton can be easily abstracted by a strong base. Actually, alcohols are very weak acids even weaker than water. Web1 Answer.
