12 **Question 12:** What is reagent A, which is necessary to complete the following conversion?**Chemical Conversion Details:**- **Reactant Structure:** The starting compound is a benzene ring with three substituents: a bromine (Br) atom, an amino group (NH₂), and a chlorine (Cl) atom, arranged with the bromine and amino groups ortho to each other.- **Reaction Conditions:** The reactant is treated with sodium nitrite (NaNO₂) and hydrochloric acid (HCl) at a temperature below 5°C.- **Intermediate Reaction Step:** The reaction results in the formation of a diazonium salt intermediate, not shown, which requires further treatment with reagent A.- **Product Structure:** The product structure is a benzene ring with bromine and chlorine atoms in the same positions as the original reactant, but the amino group is removed.**Explanation of Conversion Process:**1. **Formation of Diazonium Salt:** The initial step involves treating the amino-substituted benzene with NaNO₂ and HCl to form a diazonium ion intermediate.2. **Role of Reagent A:** Reagent A is typically a reducing agent or a nucleophile that completes the conversion process by replacing the diazonium group.3. **Final Product:** The final aromatic compound retains the original bromine and chlorine substituents, while the position formerly occupied by the amino group is now a hydrogen atom.In this reaction, reagent A is likely hypophosphorous acid (H₃PO₂), which facilitates the conversion of the diazonium salt to the plain benzene ring by reducing the diazonium group.

Greenwashing is a major problem. Companies will say they are using practices that benefit the environment while really not taking any steps to do so. An example is Terracycle - a company that is supposedly able to recycle non-recyclable plastics and by-products - but which went over a year without collecting products from any of their customers. How can consumers navigate the labels to determine if products are actually sustainable.
