Concept explainers
(a)
Interpretation:
Whether the following pair of structures is 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 formula and same molecular formula.
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. For naming the enantiomer as R or S-enantiomer, the Cahn-Ingold-Prelog rule is followed.
