The given pair of structures identical compounds, enantiomers, diastereomers, or constitutional isomers has to be identified. Concept introduction: Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer. Constitutional Isomers: A molecule having same molecular formula with different structural formulas (Difference in the connectivity of the molecule is called constitutional isomer) . Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space. Enantiomers: A compound which is non-superimposable mirror image is called enantiomers. Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers. Cis – trans isomerism (or) geometric isomerism or configurational isomerism: The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as cis isomer (or Z -isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as trans isomer (or E -isomer).

Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.

Constitutional Isomers: A molecule having same molecular formula with different structural formulas (Difference in the connectivity of the molecule is called constitutional isomer).

Stereoisomers: Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.

Enantiomers: A compound which is non-superimposable mirror image is called enantiomers.

Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers.

Cis–trans isomerism (or) geometric isomerism or configurational isomerism:

The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as cis isomer (or Z-isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as trans isomer (or E-isomer).
