Question

Which of the following compound is most acidic ? (A) Cl-CH2-CH2-OH (B)  (C)  (D)

Acidic nature is directly proportional to the stability of anion when acidic H is removed. Since in Phenol negative charge formed after the removal of acidic H will be delocalized in the whole ring. Hence it will be most stable. So phenol will be most acidic compound.
