Hi guys. Problem 50. Access to classified. They're following reactions as addition, substitution, oxidation reduction, elimination or condensation. So, before we going to the actual classification, why don't we throughout the structures off a reactant ce on the correspondent product? In each of these reactions to see how the transformation is actually taking place. In that way, we can have a better feeling off how these rations can be classified. So let's start with. And so we have two poutine post hydrogen to give poutine. So let's try out the structure off to 13. We have that of hydrogen hydrogen. So we have one, two, 34 is too right. Good, because of the number off Hodgins in depend Chain and then in is stays on saturation. Right for this double one in position to it, we were told that ate rats with hydrogen to give Bhutan. So after the reaction, the own saturation is gone. For clearly, we have the Inc off this small molecule into the reactant to give one product. So in addition, reactions we have atoms born dead toe on saturation orto unsaturated compounds to give one product. So this is clearly an addition. Reaction reason being that we have this small monocle split in two. Give atoms which are burned it. Two this unsaturated compound to get rid. Get rid off the on saturation unproduced one product. So the next one is direction off. Propane. This is the right. So we have be direction off. Propane, which is one 23 Where flooring to give to flora. Propane 212 Very well. We have this one too. Well, well on hydrogen fluoride. So this is propane, right? Directing with flooring to give to flu. Prue in on. That's my mark. So from here, you can see that this hydrogen Adam in the reactant it's actually substituted with flooring Atom in the product. Right. So and we end up produce in, um, it substituted, um, product. So remember, in substitution reaction, you have one atom for a group off atom in Molly coup replaced by another atom of group of atoms. So we have hydrogen here, replaced by Florence. So this is a substitution reaction. Right? So the next the next reaction is the reaction off or rather, the conversion off to pro panel two Propane on water. So we have 123 right well want to you? Oh, h So this is to proper No gives propane plus water. So here we have one reactant break in to give two products. So when we have reactant that has some atoms removed from it. I just sent carbon atoms. I mean on additional bond between the carbon atoms. Then that is an elimination reaction on. Clearly that is what is going on here. We have hydrogen would have will itch eliminated from this adjusts and carbon atoms to have an additional bond on DDE, the lost off small molecule. So this reaction is an elimination, actually eliminating water molecule from two proper? No. On in the process, we're actually added a new bond. So this is an elimination reaction on Fine. And we have the reaction off cycle protein plus water says cool Boutin. Oh, that plus water to give Psychlo beautiful you have. Oh, and should we have? So, in this reaction, we have the water molecules pleating us. Oh, ej um this all right on being added to this on such rated parts off the compound us oh, age on edge. I'm getting rid off the double one again. Addition, reactions. My reactions were Assam's. I led to own saturation to could use one product that is such a return, or at least with reduced saturation. So we have this oil rich on this age added to this side off the compound US Ohh and EJ I'm the own saturation is reduced. Two complete saturation to distraction is also on addition, reaction. So this is, um, kind off easy like easier wit classify reactions. These are like their structure. You be able to see clearly what is actually going on.
