Circle the carol center so we are going to discuss how can we identify coral center what is the carol center chiral center is a tetrahedral atom in a molecule bearing four different ligands or groups with long pairs also okay so in the first molecule we have c double bond carbon should be as p3 hybridized okay so this carbon is also coral center and this is also because both the carbons are coral center and are spp3 hybrid and all four groups are also different how from this carbon one group oh h second group is h third group is this carboxic acid and fourth group is this completely is completely.
01:13
That's why this carbon is coral center.
01:18
And same as for this carbon.
01:21
Why? because this carbon also have oh group, hydrogen, aldehyde and this completely group, which is present in left side.
01:31
So all the four groups are different.
01:34
That's why this molecule have two chiral center.
01:40
Two chiral center.
01:43
Okay.
01:43
Okay, like that, suppose this carbon have x, y, z and w.
01:52
So this carbon is a carol center.
01:56
If this x, y, y and j is this carol center? no, it will not carol center because y group is the same...
