Conformers can be described by which terms?

1. Epimers and Enantiomers

2. Cis and Trans

3. Anomers and Diastereomers

4. Stereoisomers and Isomers

The correct answer is: Cis and Trans

Conformers are molecules that have the same chemical formula but differ in the spatial arrangement of their atoms. They can be described by the terms Cis and Trans, which refer to the relative positions of functional groups or substituents on a double bond or ring. Epimers and enantiomers are types of stereoisomers that have different configurations around one or more chiral centers and are not considered conformers. Anomers and diastereomers are also types of stereoisomers, but they differ in their configurations at multiple chiral centers and are not considered conformers. Isomers are molecules that have the same molecular formula but differ in their chemical structure and properties. Stereoisomers are a type of isomer that differ in their spatial arrangement of atoms, such as conformers, but not all isomers are considered conformers. Therefore, the term isomers alone is not specific enough
