Welcome back, everyone through the plausible products for the given substitution reaction of benzene, we know that substitution reactions of benzene generally produce via electro pilic aromatic substitution or eas. And essentially, what we have to understand is that benzene reacts with bromine in this problem in the presence of a catalyst which is iron three bromide. And this allows us to replace one of the hydrogen atoms within benzene with bromine. Now, what are we getting? Well, essentially, first of all, we're going to redraw the six member ring or basically benzene itself. And our next step is to essentially replace one of the implicit six hydrogen atoms. We have six of them, right, with bromine. So let's go ahead and do that. Now, the remaining bromine atom essentially gets bonded to that hygiene that we have lost from benzene. So our by-product would be HBR right? And this is how we can simply get our products. Let's label them as our final answer. Thank you for watching.
