A compound ‘X’ is acidic and it is soluble in NaOH solution, but insoluble in NaHCO3 solution. Compound ‘X’ also gives violet colour with neutral FeCl3 solution. The compound ‘X’ is :
The given problem involves identifying the compound 'X' based on its chemical properties. Let's analyze the given properties of compound 'X' one by one to determine its identity.
The compound 'X' is acidic and is soluble in NaOH solution. This indicates that 'X' could possibly be a phenol as phenols are weak acids and can dissolve in NaOH to form phenoxide ions.
'X' is insoluble in NaHCO3 solution. Carboxylic acids, being stronger acids than phenols, will react with NaHCO3 to produce carbon dioxide gas. Hence, 'X' is likely not a carboxylic acid because it does not dissolve, confirming that 'X' behaves like a weaker acid than carboxylic acids.
Additionally, 'X' gives a violet color with neutral FeCl3 solution. This test is specific for phenols, which form a violet-colored complex with FeCl3.
Based on these properties, we can conclude that compound 'X' is a phenol. Among the given options, the second image represents phenol.
Therefore, the compound 'X' that matches the given characteristics is phenol.
Let's summarize the conclusions:
Phenol is weakly acidic, dissolving in NaOH to form phenoxide, but not in NaHCO3.
Phenol reacts with neutral FeCl3 to give a violet color, a classical indicator of phenolic groups.
Thus, the correct answer is the structure shown in the second image option.
