Question

the oxygen in phenol and phenolate ion show opposite indictive effect​

Answer 1

• The aromatic character of the phenolate ion is restored by the formation of ion pairs ... Thus, cesium phenolate still shows charge localization on the oxygen atom. ... Certainly, inductive effects have a large participation in the stabilization of the ... which is the opposite to that corresponding to the influence of the cation

Answer 2

Answer:

In phenol, oxygen is the more electronegative atom (vs carbon). Therefore, the oxygen-carbon bond is polarized somewhat and the electrons are pulled towards the oxygen atom.

In phenolate, the oxygen bears a full negative charge. This high charge density pushes electron density back into the pi system.
