why is water more acidic than alcohol---C2H5OH?
pl. ans.very imp.
Ethanol is an alcohol. Alcohols, in general are weaker acids than water. This is because the OH group in alcohols is less polar than the OH group in water. The electron releasing nature of the R group in alcohols decreases the polarity of the OH bond, leading to decrease in acid strength of alcohols. As a result, water is a better proton donor than alcohol. Also, the alkoxide ion is a better proton acceptor than the the hydroxide ion, suggesting that the alkoxides are stronger bases.
Thus, ethanol is a weaker acid than water.
