Dear students, we have to determine the r or s configuration of this molecule, whether it is r or s.
00:11
So for this, we have to arrange the groups in the priority order.
00:16
So for that, we have to see the first atom directly attached to the chiral carbon, its atomic number.
00:24
Now if we see the atomic number, bromine is the highest atomic number, so it will be ranked oxygen here, 2.
00:31
In these two groups, carbon is directly attached.
00:36
Then we will see the next atom, cho means it is the group is like this and ch2oh means coh, here h, here h.
00:50
It is like this.
00:52
So first atom is carbon, then we will see the next higher priority atom, here oxygen, here also oxygen.
00:57
Now because here double bond is there, we can write like this, this is as carbon and here we can attach one oxygen...
