In problem 9 .28, we are given specific starting materials and products.
00:09
And we are to provide the reagents that will convert the starting material into the final product.
00:15
In the first reaction, we need a reagent that will convert our triple bond into our markov -ketone.
00:21
And to do this, we are going to use acid and mercury sulfate.
00:37
This will proceed with a carbocation intermediate.
00:43
And eno and keto products will form.
00:47
However, the keto product will be the major product.
00:52
Now let's look at reaction b.
00:54
In reaction b, we need the non -markovnikov version of the reaction in part a.
01:01
And to do this, we have two steps.
01:05
First will be borraine, which will add to the terminal side of the triple bond.
01:13
This will be in thf, and then the second step will be oxidation using hydrogen peroxide.
01:32
Now for part c, in part c, we need to convert, we need to add a carbon or methyl group to the end of the triple bond.
01:41
And this will also take two steps.
01:45
In the first step, we'll use a strong base to remove the terminal hydrogen from the triple bond...
