Which of the following compounds is most acidic?
Cl-CH2-CH2-OH
A.
The correct order of acidic strength is
Phenols are stronger acids than alcohols because the phenoxide ion left after the release of a proton is stabilised by resonance but the alkoxide ion is not. Further, the electron-withdrawing groups (-NO2) whch stabilise the phenoxide, on by dispersing the negative charge relative to phenol increase the acidic strength of phenols, whereas electron donating group (-CH3) which destabilise the phenoxide ion by intensifying the negative charge relative to phenol tend to decrease the acidity of phenols.
Phenol + CCl4 + KOH → X;
