Chapter 21, Problem 64A

Interpretation Introduction

Interpretation:

The similarity and difference in two isomers should be explained.

Concept introduction:

The molecules having same molecular formula but the structural arrangement of atoms is different in the molecule are said to be isomers of each other.

Explanation of Solution

The similarity in isomers is that all the compounds possess same molecular formula and the difference being in structural arrangement of atoms in the molecules.

The example of two isomers are:

Isomer I:

Isomer II:

Both the isomers possess same molecular formula, that is, ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$ but the arrangement of atoms in both the molecules are different as in isomer I all the atoms are present in straight chain, hexane and in isomer II all the parent chain is of four carbon atoms and 2 methyl substituents are present at carbon-2, 2, 2-dimethylbutane.
