Question 4 Not yet answred So that they are indistinguishable. If they are enantiotopic they are mirror images of each other but not equivalent. If they are diastereotopic they are connected Marked out of 8.00 P Flag question Topicity is the relation between two atoms or groups within a molecule. If atoms or groups are equivalent, the molecule or bonds of a molecule can be rotated in the same fashion but not equivalent or enantiotopic. If they are constitutional heterotopic, they are connected differently in a molecule. Answer whether atoms or groups of the given topicity are indistinguishable by NMR (symmetric environment) and/or by organisms (asymmetric environment). Enantiotopic atoms or groups are indistinguishable by NMR. Diastereotopic atoms or groups are indistinguishable by NMR. Diastereotopic atoms or groups are indistinguishable by organisms. Equivalent atoms or groups are indistinguishable by organisms. Constitutional heterotopic atoms or groups are indistinguishable by organisms. Choose... Enantiotopic atoms or groups are indistinguishable by organisms. Equivalent atoms or groups are indistinguishable by NMR. Constitutional heterotopic atoms or groups are indistinguishable by NMR Choose... false true

Explanation / Answer

Question 4)

a) Enantiotopic atoms or groups are indistinguishable by NMR : True

Enantiomers would have same NMR under achiral environment

b) Diastereotopic atoms or groups are indistinguishable by NMR : False

Diastereomers have different NMR shifts and are distinguishable by NMR

c) Diastereotopic atoms or groups are indistinguishable by organisms : False

Diastereomerslike as in enantiomers would interact differently with organisms

d) Equivalent atoms or groups are indistinguishable by organisms : True

e) Constitutional heterotopic atoms or groups are indistinguishable by organisms : False

As the constitutional structure changes so does the functional group and thus it would have a different interaction with the organism.

f) Enantiotopic atoms or groups are indistinguishable by organisms : False

The organisms responds to a specific enanatiomer in a different way as compared to it other enantiomeric isomer.

g) Equivalent atoms or groups are indistinguishable by NMR : True

h) Constitutional heterotopic atoms or groups are indistinguishable by NMR : False

Constitutional isomers say an ether and an alcohol of the same molecular formula would differ in their NMR
