Draw the structural formula for the product in each of the following reactions:

d. Structural formula showing a reaction between an alkene and water, with a proton symbol indicating hydration.

Accepted Answer

All right. Hi, everyone. So for this question, lets go ahead and give the structure of the compound formed in the reaction given below here we have E 27 dimethyl oct 14 reacting with water in the presence of acid as a catalyst. And in this case, we can see all four answer choices labeled A through D. Now recall that the reaction provided is an example of the hydration of an OK, in which water is added across both carbons of the starting a key. Now when we say that water is added across both carbons, one carbon of the starting double pond receives a hydrogen atom and the other receives a hydroxy or an oh group. Now, with this in mind, we also have to recall that hydration is an example of Markov Niko edition. In other words, Hi, sorry. The hydroxy group would add on to the more substituted carbon atom from the starting alkene. In other words, the hydroxy group would add on to the carbon that has less hydrogen atoms attached. But what I want to point out here is that in the structure of E 27 dimethyl ox four carbons four and five that participate in the double wand are actually symmetrical because they are both attached to the same groups. So because of this, the hydroxy group can attach itself onto either carbon. There is no preference in this case because both carbons are equivalent. So here when drawing out the final product, the carbon skeleton is not going to change necessarily. And what I mean by that is that there are going to be the same number of carbon atoms in the product compared to the starting material. So in this case, I'm going to first go ahead and draw out my carbon chain and add on my methyl substituents on positions two and seven because that is not going to change. However, in my final product, there would no longer be a double bond in between carbons four and five. Instead, there would simply be a single bond. And as discussed previously, the hydroxy group can add on to either carbon in this case. So because I drew the hydroxy group on carbon four, carbon five would receive the hydrogen atom from our water molecule. And so this results in an alcohol as our final product, specifically 27 dimethyl four octonal. And so this matches the structure of or the structure provided in option B of the multiple choice. But I do want to briefly discuss why the remaining three answer choices are incorrect. Starting off with option eight. The reason why option A would be incorrect is because recall that hydration does not result in the addition of two hydroxy groups. Rather it results in the addition of only one and so option C is incorrect for the same reason, right, you would only see one hydroxy group as opposed to two in the product of a hydration reaction. Whereas option D is incorrect because even though the hydroxy group is attached, there is still a double bond in between carbons four and five, which would not be present in the product. And so with all that being said, thank you so very much for watching and I hope you found this helpful.
