Concept explainers
(a)
Interpretation:
Identify the given pair of structures as identical molecules, enantiomers or isomers of some other sort.
Concept introduction:
Structural or constitutional Isomers can be defined as the molecules with same molecular formula and different structural formula. They are molecules in which the bonded atoms have different bonding with each other although the number of molecules is same. Identical molecules are molecules which have same structural formulae and same molecular formulae. On the contrary, enantiomers are optical isomers which can rotate the plane polarized light either clockwise or anticlockwise. These molecules must have at least one chiral C atom which is bonded with four different groups. They are named as R and S configuration. The R/S naming follows the Cahn-Ingold-Prelog Rules for naming the enantiomer as R or S-enantiomer.

- Build a model (attach a photo) for any of the following compounds. What is their relationship: (i) Identical in the same conformation, (ii) conformers, (iii) enantiomers, (iv) diastereomers, (v) constitutional (structural) isomers or none of (i) – (v)? H OH H. HO $Bu CI $Bu Relationship:arrow_forwardAre they chiral in nature? Are they enantiomeric?arrow_forwardWhat is the relationship for the following pairs of compounds. The options include constitutional isomers, not isomers, enantiomers, conformers, identical, resonance structures.arrow_forward
- For each of the following pairs, give the relationship between the two compounds. You many ignore conformational isomerism here, and any conformers may be considered to be identical compounds.arrow_forwardWhich molecule/molecules are not chiral?arrow_forwardDraw two constitutional isomers that share the molecular formula C2H,N. Your structures will have the same molecular formula but will have different connectivities.arrow_forward
- 9) There are 3 different cyclopropane molecules with the formula GHĄC12. a. Draw and build the 3 molecules. b. Below each drawing, name each molecule with correct nomenclature. Label a pair that are constitutional isomers. d. Label a pair that are stereoisomers (or configurational isomers). С.arrow_forwardShow in each of the pairs below whether the two structures are structural isomers, stereoisomers, or different Conformations of the same compound.arrow_forwardIdentify the isomers in the picture.arrow_forward
