Hello Student
A compound is more acidic when it gives more stable anion after releasing a proton.
Amine will loose a proton to give amide ion while an alcohol will give an unstable alkoxide ion by releasing a proton.
In case of alcohols oxygen atom is more electronegative than nitrogen atom, so it will strongly attract the positive species, and so alkoxide ion becomes more stable than amide ion.
Hence, the amines are less acidic than alcohol of same molecular masses.
