Hi guys, let's solve problem 8 .32.
00:03
We need to predict the product for the given reactions.
00:07
So here we are having a very complicated molecule, cholesterol, but we need to notice that there is only one double bond given in this molecule.
00:17
And we are going to have reaction only on this side of this molecule.
00:25
And for the first reaction, croman is going to add to the double bonded carbons here and it will form a dibromo alkan so the whole structure will be written only the double bond will be broken and roman is going to add so bromine is going to add at these two particular positions and this is a di brommo alkan for the second one hydrogen halide is going to direct with this carbon carbon double bond and it will form bromo alken in this case, the bromine group is going to add to the most substituted carbon.
01:07
So the most substituted carbon is this one, where the bromine is going to add, and hydrogen is going to add to the other one.
01:22
For the photon, osmium tetroxide is going to react with the double bond, and it will give us the diethyl, and the hydroxyl groups will be on the same side.
01:34
Of the plane of the molecule.
01:45
For the fourth one, the reaction of the, in this case, it is hydroboration oxidation reaction...
