Explanation:
Phenol is an organic compound with a hydroxyl (-OH) group attached to a benzene ring. It is a weak acid due to the electron-donating effect of the benzene ring, which stabilizes the negative charge on the oxygen atom of the -OH group. When phenol is dissolved in water, it partially dissociates into phenoxide ion and hydrogen ion (H+).
NaHCO3 is a weak base and reacts with acids to form salt, carbon dioxide, and water. The reaction between NaHCO3 and an acid is an acid-base neutralization reaction. The products of the reaction are salt (NaX), carbon dioxide gas (CO2), and water (H2O).
Now let's consider the reaction between phenol and NaHCO3:
C6H5OH + NaHCO3 → No Reaction
There is no reaction between phenol and NaHCO3 because phenol is a weaker acid than carbonic acid (H2CO3), which is formed when NaHCO3 reacts with water. The acid-base reaction between NaHCO3 and water can be represented as:
NaHCO3 + H2O → H2CO3 + Na+ + OH-
Carbonic acid (H2CO3) is a stronger acid than phenol and reacts with NaHCO3 to form salt (NaX), carbon dioxide gas (CO2), and water (H2O).
Therefore, the correct answer is option 'A': Phenol does not react with NaHCO3 because phenol is a weaker acid than carbonic acid.

Phenol is acidic but does not react with sodium carbonate or bicarbonate because it is weakly acidic and thereby do not have the strength to substitute or give away it's H + ions to a weak base .
