WebVandaag · The pH of 1-Butanol is very close to 7, because of which it is to be regarded as a very weak acid. On the same carbon, if we attach a chloro group (electron-withdrawing group through negative inductive effect) we will get a compound as 1-Chloro butanol. This compound will have a pH lower than 1-butanol, which is it will be more acidic in nature.
