Hey everyone and welcome back in today's video, we are going to solve the following problem. How can the following transformation be achieved? You can use any regions is required. If we look at our starting material, we understand that this is a conjugated key zone because this part where we have a double bond, we can consider this part to be our elkin. In this part to be our carbon ill or a key zone. We noticed that the two double bonds are basically linked, there's no spacing in between them which would contain an sp three hybridized carbon atom. Indeed, these three carbon atoms are sp two hybridized. So this must be conjugated ketone. Now, what we're forming is just a key tone itself. We don't have that double bond anymore at this position, meaning we noticed that this is the only change. We're essentially adding two hydrogen atoms across our double bond and reducing it. Right? So first of all, let's keep in mind that this reaction is a reduction reaction because our double bond becomes a single bond. So we are adding two hydrogen atoms across it to produce an al kill chain out of an alkaline. Now, number two, we understand that, that this is a reduction. We essentially want to choose a reducing agent and let's recall that not every reducing agent will really work for us. We have to think about the most selectivity. For example, if we actually want to reduce a keystone into an alcohol, we would use one reducing agents such as sodium world hydride or lithium aluminum hydride. But this region will not interact with the al Qaim part. But if we only want to reduce the al Qaim part, we simply recall that the region for that is hydrogen gas in the presence of platinum catalysts or palladium if you wish. Now, this Regent in particular is used to reduce Elkins to al canes and it doesn't affect the carbonell group to a significant extent. So in the majority of cases, the carbon group will be unaffected at Soul as long as we keep it at low pressure. That's in order to keep our carbonell group over there and just reduce the ALC impart itself. We are going to propose our catalytic hydrogenation, right hydrogen in the presence of platinum catalysts. So these are our reagents needed for this reaction. Let's label these as our final answer and we may simply conclude that the correct answer choice.
