Chiral carbon isomers

WebYou have the carbons on both of them. This carbon looks like a chiral center. It's bonded to one, two, three different groups. You might say, oh, it's two carbons, but this is a methyl group, and then this side has all this business over it, so this is definitely a chiral carbon. And over, here same thing. It's a chiral carbon. WebWe expect $16~(=2^{n-1})$ isomers, with the C4 carbon being pseudo-chiral. To avoid a really large table, we observe that the number of meso isomers is easily countable (<< number of enantiomers). ... Molecule …
