    option C is correct Para chloro phenol is more acidic than para fluoro phenol. Explanation:- When you draw all the resonance structures of the conjugate base of both p-chloro phenol and p-fluoro phenol, you'll see that the p-chloro phenoxide ion will have an extra resonance structure. This is because of the negative charge delocalizing on the vacant d-orbitals of chlorine atom present in the para position and this is not possible with fluorine atom. Thus, the conjugate base of p-chloro phenol is more stable and hence a weak base. So, p-chloro phenol is more acidic than p-fluoro phenol.
