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. WebThe cleavage of O−H bond Both alcohols and phenols readily release proton (the H + ion attached to the oxygen atom). Acidic character Take a look at the reactions below : In above reactions, alcohols and phenols are donating a proton which suggests that they are acidic in nature. Acids are proton donors whereas bases are proton acceptors. WebThe cleavage of the C-O bond in ethers requires extreme conditions or changes with excess HX and high temperature. The reaction of dialkyl ethers with HX gives two molecules of alkyl halides. R-O-R+HX→R-X+R-OH Alkyl aryl ethers are cleaved at the alkyl oxygen bond due to the more stable aryl oxygen bond, and breaking this bond is tough. fire-roasted cherry tomato salsa
