Question

why alcohol are less acidic than water

Answer 1

Since -OH - > -OR - , hence water is more acidic than alcohols. Water is a betteracid than alcohol because of the electron donating nature of the alkyl group attached to the oxygen which destabilizes the hydroxide(in the case of alcohol,Alkoxide) ion and makes it tougher for the oxygen to donate the proton.

hope it helps u ^_^

Answer 2

● In alcohol O-H group is attached

with alkyl group . That alkyl has

tendency to show +I effect.

●The alkyl group releases electrons C-O bonds toward oxygen atom and increase s electron density around it and therefore polarity of O-H bond decreases .

●As a result the tendency of oxygen to withdraw electrons in O-H bond towards itself decreases nd therefore proton release become difficult .

Thus it all happen due to +I effect of alkyl group .
