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. (wikipedia.org)
Some examples of this configurational stereoisomerism (sometimes called geometric isomerism) are shown below. (msu.edu)
The isomers are molecules with equal molecular formula, but with a different structure (structural isomerism) or different spatial orientation (stereoisomerism). (knowswhy.com)

Carbon atom3
In the next two examples, each double bond carbon atom has two different substituent groups and stereoisomerism exists, regardless of whether the two substituents on one carbon are the same as those on the other. (msu.edu)
The carbon atom, where stereoisomerism occurs is the acetal/hemiacetal carbon (called also anomeric carbon). (knowswhy.com)
The carbon atom, where stereoisomerism occurs can be any single stereogenic center. (knowswhy.com)
Double bond2
Stereoisomerism about double bonds arises because rotation about the double bond is restricted, keeping the substituents fixed relative to each other. (wikipedia.org)
In the first example, the left-hand double bond carbon has two identical substituents ( A ) so stereoisomerism about the double bond is not possible (reversing substituents on the right-hand carbon gives the same configuration). (msu.edu)
