Interpretation:
Three possible structures for the constitutional isomers of molecular formula
Concept Introduction:
There are two main classes of isomers − constitutional isomers and stereo isomers.
Constitutional Isomers have the same molecular formula but differ in the way the atoms are connected to each other.
Chirality is the presence of an asymmetric carbon center in a molecule and a molecule which contains a chiral center cannot superimpose on its mirror image. To consider as chiral, molecule or object and its mirror image should not superimpose. To consider as achiral, molecule or object and its mirror image should be superimposed with each other.
In the above diagram, where C is the chiral center/ asymmetric carbon center.
A, B, D, E are four different
