What alkene could you use to make the following products? Draw the structure of the alkene, and tell what other reagent is also required for the reaction to occur.

c. Structural formula of an alkene with a bromine atom attached, indicating a hydrohalogenation reaction.

Accepted Answer

All right. Hi, everyone. So this question says to draw the structure of the all keen and identify the other reagent required to produce the following product. Now, the product in question happens to be two bromo pancake because we have a five carbon chain with a bromine atom on carbon two. Now notice how the following product is a mono ocular Halide in which we have an all cane with only one halogen atom. And so the starting material must be an all keen. So an all keen has to react with something else to produce an all kill hide with only one halogen atom. Now, that reaction if you recall is referred to as the hydro halogen nation of and all keep in which an alkene reacts with a compound hx where X is a halogen to produce an oy highlight. Now, for the purposes of finding the alkene product, recall that one carbon atom of the alkene receives a hydrogen whereas the other receives the halogen atom. So if we consider the structure of two Bromma pentane carbon two must be part of the ane if that is where bromine is attached, right. So it's worth noting that we have two possibilities because we can either draw a double bond in between carbons two and three or in between carbons one and two. There are two possible alkenes that can form the same product. But for the purposes of this question, we're only going to focus on one, namely an alkene in between carbons, one and two of the structure, right? So enjoying the identity of the all keen, my first step is to remove my bromine atom from carbon two and then remove one hydrogen from carbon one to create a double bond in between them. So carbons three through five are going to stay the same. So that's ch three ch two, ch two, but carbon two is going to remain ach with a double bond in between itself and carbon one which now has one less hydrogen. So it's a CH two. And so with respect to finding oops, with respect to finding the other reagent, the other b agent necessary for hydro halogen is HX where X is the halogen. Now, because we have bromine in our intended product, the other reagent must therefore be H pr and there you have it. So here we have one ane that can be used to produce the following ide T roopa with the other reagent being H pr. So with that being said, thank you so very much for watching and I hope you found this helpful
