Interpretation Introduction
Interpretation: To determine the compound obtained upon conversion of
Concept introduction: Sulfate assimilation is the process used for the production of hydrogen sulfide. The starting material for sulfate assimilation is sulfate ion. It is an oxidation-reduction process as the sulfur in sulfate ion is in oxidized form and in hydrogen sulfide it is present in the reduced form.

- Which carbocation is more stable?arrow_forwardAre the products of the given reaction correct? Why or why not?arrow_forwardThe question below asks why the products shown are NOT the correct products. I asked this already, and the person explained why those are the correct products, as opposed to what we would think should be the correct products. That's the opposite of what the question was asking. Why are they not the correct products? A reaction mechanism for how we arrive at the correct products is requested ("using key intermediates"). In other words, why is HCl added to the terminal alkene rather than the internal alkene?arrow_forward
