Phenol, C6H5OH, has a Ka of 1.3×10−10. 1.Write out the Ka reaction for phenol. 2. Calculate Kb for phenol’s conjugate base. 3.Is phenol a stronger or weaker acid than water? explain why.
a. C6H5OH + H2O ---> C6H5O- + H3O+b.Kb(C6H5O−)=Kw/Ka(C6H5OH)Kb(C6H5O−)=Kw/Ka(C6H5OH)Calculate the value of the base dissociation constant of phenoxide ion by substituting the given value of the acid dissociation constant of phenol...

Explain how the nature of the substituent affects the basicity of the substituted aniline.
Electron-donating substituents such as CH3 increase the basicity of aniline. Electron withdrawing group substituents such as halogens or a nitro group decrease the basicity of aniline.
