(A) Phenols are acidic & react with alkalies like NaOH but do not react with Na₂CO₃ and NaHCO₃ solutions 
(R) ${\mathrm{CO}}_3^{-2}\mathrm{\&}{\mathrm{HCO}}_3^{-}$ ions are less basic than phenoxide ion

Both ‘A’ and ‘R’ are true and ‘R’ is the correct explanation of ‘A’.

‘A’ is false and ‘R’ is false
