Stereoisomers have identical molecular formulas and arrangements of atoms. They differ from each other only in the spatial orientation of groups in the molecule. The simplest forms of stereoisomers are cis and trans isomers, both of which are created by the restricted rotation about a …
Conformational Isomers - Compounds of the same structure that differ in rotation around one or more single bonds. Configurational Isomers or Stereoisomers
Your hands are (roughly) enantiomers. both are optically active is true of enantiomers. Stereoisomers have the same functional groups and connectivities, they differ only in the arrangement of atoms and bonds in space. Conformational isomers (or conformers or rotational isomers or rotamers) are stereoisomers produced by rotation (twisting) about σ bonds, and are often rapidly interconverting at room temperature.
All stereoisomers are either configurational isomers or conformational isomers. Configurational Isomers: Two molecules with … This is analogous to putting a mirror on the side of a molecule. However, when you spin your legs so that they are now straight out in front of you, it's as if you put the mirror behind one of your legs and the other one was the mirror image from behind. Same molecule just spun in a different direction. Chirality and Stereoisomers. Stereoisomers are isomers that differ in spatial arrangement of atoms, rather than order of atomic connectivity. One of their most interesting type of isomer is the mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror image of one another.
Stereoisomers have identical molecular formulas and arrangements of atoms. They differ from each other only in the spatial orientation of groups in the molecule.

Two molecules that are the same stereoisomer as each other might be in different conformational forms or be different isotopologues.
But you may be asked to draw 4. Label each pair of compounds below as a conformational isomers b stereoisomers from CCN 2274 at Hong Kong Community College

Conformational isomers (or conformers or rotational isomers or rotamers) are stereoisomers produced by rotation (twisting) about σ bonds, and are often rapidly interconverting at room temperature. Click to see full answer . A breakdown of definitions involved with describing stereoisomers. Configurational and conformational isomers are described and resolved into enantiomers, d
In chemistry, conformational isomerism is a form of stereoisomerism in which the isomers can be interconverted just by rotations about formally single bonds. While any two arrangements of atoms in a molecule that differ by rotation about single bonds can be referred to as different conformations, conformations that correspond to local minima on the potential energy surface are specifically called conformational isomers or conformers.

An example would be butane vs. The caution about reorienting and looking at other conformations is important.
