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). WebThe following discussion uses the various isomers of dichlorocyclohexane as examples. The 1,1-dichloro isomer is omitted because it is an unexceptional constitutional isomer of the others, and has no centers of chirality (asymmetric carbon atoms).

WebStereochemistry focuses on stereoisomers. In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.
