Structural isomers differ in their connectivity of atoms and/or the order in which atoms are bonded to each other within molecules. They have different structural formulas but the same molecular formula. Conformational isomers, on the other hand, refer to different spatial arrangements of the same molecule that can be interconverted by rotations around single bonds. These arrangements are typically stable and exist as different conformations of the same molecule without altering its connectivity.
Conformational isomers specifically refer to different spatial arrangements of the same molecule that can be interconverted by rotations around single bonds. These different conformations do not involve changes in the connectivity of atoms but rather in the spatial orientations of the molecule.
Structural isomers are a broader category that encompasses all types of isomers that differ in their molecular structures. This includes isomers with different connectivity of atoms (structural isomers), as well as those that differ in their spatial arrangements (stereoisomers).
Isomers refer to different compounds that have the same molecular formula but different structures or spatial arrangements. Conformers, however, specifically refer to different spatial arrangements of the same molecule that can be interconverted by rotation around single bonds. Conformers are usually stable and represent different conformations of the same molecule.
Configurational isomers are a type of stereoisomers that cannot be interconverted without breaking covalent bonds, such as enantiomers and diastereomers. They differ in the spatial arrangement of atoms around one or more chiral centers. Conformational isomers, on the other hand, refer to different spatial arrangements of the same molecule that can be interconverted by rotation around single bonds without breaking any covalent bonds. Configurational isomers are distinct in their fixed spatial arrangements, while conformational isomers represent different spatial orientations that are interconvertible.
