Question

(i)

(ii)

(iii)

The relationship between the pair of compounds shown above is respectively,

• A. enantiomer,diastereomer,diastereomer
• B. enantiomer,enantiomer,diastereomer
• C. enantiomer,homomer(identical),diastereomer
• D. homomer(identical), diastereomer,geometrical isomer

Answer 1

Answer: (C)

enantiomer,homomer(identical),diastereomer

Answer 2

The correct answer is option (C): enantiomer,homomer(identical),diastereomer

Enantiomers are the stereoisomers which are non-superimposable mirror images of each other. Enantiomers have opposite configurations at the respective asymmetric centre.

These molecules have the same configuration. So, they are identical.

Diastereoisomers are non-identical non-mirror images of each other having the same bonding sequence. They arise when two or more non-mirror stereoisomers of a compound have different configurations at one or more (not all) of the respective stereocentres.

Structural isomers have different connectivity of atoms/species.
