Question

Correct relation between above compounds.

• A. I and II are structural isomers
• B. I and III are diastereomers
• C. I and II are eneantiomers
• D. II and III are enantiomers

Answer 1

The correct option is A I and II are structural isomers

Due to different connectivity of atoms in $I$ and $II$, they are not enantiomers or they are only structural isomers. $(II,III)$ has also different, connectivity of atoms so, they are not enantiomers . $(I,III)$ are having $(R,S)$, $(R,S)$ so same compound
