The ionization constant of phenol is higher than that of ethanol because : [2000]
  • a)
    phenoxide ion is bulkier than ethoxide
  • b)
    phenoxide ion is stronger base than ethoxide
  • c)
    ph en oxide ion is st abilized t h r ough delocalization
  • d)
    phenoxide ion is less stable than ethoxide
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
The ionization constant of phenol is higher than that of ethanol becau...
The acidic nature of phenol is due to the formation of stable phenoxide ion in solution
The phenoxide ion is stable due to resonance.
The negative charge is delocalized in the benzene ring which is a stabilizing factor in the phenoxide ion and increase acidity of phenol. wheras no resonance is possible in alkoxide ions (RO)derived from alcohol. The negative charge is localized on oxygen atom.
Thus, alcohols are not acidic.
