ANSWER

Increasing order of acidity is ethanol < water < phenol. The phenoxide ion obtained after the removal of a proton is stabilized by resonance whereas the ethoxide loan obtained after the removal of a proton is destabilized by +I Effect of −C

group. Therefore, phenol is a stronger acid than ethanol, On the other hand, ethanol is a weaker acid than water because electron releasing −C

• group in ethanol increases the electron density on oxygen and hence the polarity of O−H bond in ethanol decreases which results in the decreasing acidic strength

Answer:

enthanol < water < ethylene < diol<glycrrol
