Configurational Isomers: Configurational isomers are stereoisomers that cannot be converted into one another by rotating the molecule around a single bond.

Conformational Isomers: Conformational isomers are stereoisomers that can be converted into one another by rotating the molecule at a single bond.

Types of Isomers

Configurational Isomers: There are two types of configurational isomers as geometrical isomers and optical isomers.

Conformational Isomers: There are four types of conformational isomers as eclipsed conformation, staggered conformation, gauche conformation and anti conformation.

Rotation of the Molecule

Configurational Isomers: The rotation of the molecule around a single bond does not give its isomer in configurational isomers.

Conformational Isomers: The rotation of the molecule around a single bond can give multiple isomers in conformational isomers.

Conclusion

Configurational and conformational isomers are two different types of isomers. The main difference between configurational and conformational isomers is that configurational isomers cannot be obtained by rotating the molecule around a single bond whereas conformational isomers can be obtained by rotating the molecule around a single bond.
