Detailed Solution
Download Solution PDFConcept:
From the given data, we can infer that, when the compound reacts with Acid, it becomes insoluble.
When it reacts with a base, it becomes soluble. Hence, the compound is acidic in nature.
While reacts with Br2/H2O, it becomes an unsaturated compound and results in decolourization.
Phenol is acidic in nature while Aniline is basic in nature. Phenol is insoluble in dil. HCl but soluble in NaOH to form Sodium phenol.
Phenol decolourize Br2 water to give 2, 4, 6 – tribromophenol
Here, option (c) and (d) cannot become an unsaturated compound due to their bond formation.
The organic compound that satisfies all the qualitative analysis given above is Phenol.
