Question

Why para flouro phenol is more acidic than phenol?(while I is distance dependent and insignificant after 3rd member)

Answer 1

Please mark my answer as brainlienest

Explanation:

Whenever an electronegative group is present in ortho/para position, it increases acidity of the material(here it is p-flourophenol). It attracts electron density of the armotic ring towards itself, eventually decreasing electron density on the oxyzen atom of O-H group

Answer 2

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.
