Hint: The given product name is p-amino azo benzene. The structure of the p-amino azo benzene and the structure of diazonium chloride are as follows.
Complete step-by-step answer:- In the question it is given that to find the chemical name which is going to react with diazonium chloride to give p-amino azo benzene.
- First we should know the structure of the p-amino azo benzene and the structure of diazonium chloride.
- The structure of p-amino azo benzene and the structure of diazonium chloride are as follows.
- We have to find the chemical A in the below equation.
- Coming to the options, option A. The chemical is A. Phenol. If we will take we get p-hydroxy azobenzene as the product and the chemical reaction is as follows.
- Therefore we are not getting p-amino azo benzene if we will take A is phenol. So option A is wrong.
- Coming to option B, Benzoic acid. The chemical reaction is as follows.
- Therefore option B is also not correct because we didn’t get the product that we need.
- Coming to option C, Alcohol. The chemical reaction is as follows.
- Therefore the option C is also wrong.
- Coming to option D, Aniline. The chemical reaction is as follows.
Therefore the option D, aniline is correct.
Note:By using diazonium chloride we can prepare various types of products. For example by using diazonium chloride we can prepare p-amino azo benzene as the product. It is an azo dye useful for various purposes.
