So here in this question, firstly, let us determine how do we assign r &s nomenclature.
00:06
So in determining, determining, determining r and s nomenclature, the first step is determine priority of atoms or groups.
00:35
Or groups or groups based on their molar mass and label them 1, 2, 3 and 4.
00:44
Then draw arrow, draw arrow joining 1, 2, 3 and 4 in a sequence.
01:03
In a sequence.
01:07
Now, if arrow is clockwise, if arrow is clockwise, it is as, it is r.
01:23
And if arrow is anti -clockwise, it is as.
01:38
Now, let's draw a compound.
01:42
Here we are drawing one benzene ring.
01:49
This side it is bonded to oh group and this side it is again bonded to oh group.
01:55
It has hydrogen over here and hydrogen over here and hydrogen over here.
02:04
But over this side it is bonded to one carbon which is bonded to one oh group and one hydrogen group...
