Question

Indicate whether each of the structures in the row is an enantiomer of, is a diastereomer of, or is identical to the following structure: HO Drag the appropriate items to their respective bins Reset Help OH HO HO OH OH OH OH enantiomer diastereomer identical compound

Answer 1

The structure given is Determine R/S in above structure: rightarrow The configuration comes out to be (R) due to clockwise rotation. but, since the lowest priority group is present above the plane, the configuration reverses and becomes (S). rightarrow check the 1st structure: (R) rightarrow Therefore H is above rightarrow configuration reverses the plane rightarrow This is identical to structure (I). \r\n rightarrow check the 2nd structure: - S rightarrow Because H is above the plane, so configuration is reversed and becomes (R) The configuration of each chiral centre is reversed. Therefore this forms non-super imporable rightarrow enantiomer mirror image rightarrow check the 3rd structure: - This is not a mirror image of structure (I). This becomes diastereomer. rightarrow check the 4th structure: - rightarrow 'R' reversed to 's', as H is above the plane. rightarrow This is identical to structure I.
