# Which is more activating among Phenol, Sodium Phenoxide & Anisole? Also arrange them in increasing order of their activating effect

This is in reference to Kolbe's Reaction, actually I think that Sodium Phenoxide is the most activating because, in Kolbe's Reaction we don't make react $$\ce{CO2}$$ directly with phenol for the electrophilic substitution(Maybe because of it's comparatively less activating effect), but we do make Sodium Phenoxide react with $$\ce{CO2}$$ (Maybe because of it's comparatively more activating effect) so that it will get attach to the Ortho position of Benzene Ring. Along with this, please also tell me why in Kolbe's Reaction, the main product is Ortho directing & in most of other reactions, the main product is para directing?

Out of $$\ce{O-}$$, $$\ce{-OH}$$ and $$\ce{-NH2}$$, I would say that O- is the hardest nucleophilic centre,so by HSAB, phenoxide should be more activated.
For Kolbe's reaction, since it is carried out in basic medium, so ortho position gets more activated as $$\ce{O-}$$ has a positive mesomeric as well as a positive inductive effect on the molecule
