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. WebGeometric isomers. Geometric isomers also have the same molecular formula and the same pattern of covalent bonding but differ in how atoms are spaced around a double covalent bond, especially in a carbon-to-carbon double bond. For example, consider the molecule butene (C 4 H 8).
