Chapter 7, Problem 6E

Interpretation Introduction

Interpretation:

The name of each of the given molecule needs to be determined. The relationship between the given pair of atoms in previous question needs to be checked.

Concept Introduction: The possible relationship between two structures depends on the molecular formula and structural arrangement of atoms in the molecules.

The possible relations are as follows:

Identical: Two molecular structures are identical if they have same molecular formula as well as same arrangement of atoms. The bonding substituent and their positions are same in the identical molecules.

Conformers: Two molecules are said to be conformer if they have different orientation of atoms by rotation around a single bond. They are also known as conformational isomer. For example, eclipse and staggered conformation.

Configurational isomer: They cannot be converted into one another due to the rotation around a single bond. For example, geometric and optical isomers. They can be interconverted after breaking of old bonds and making of new bonds.

Constitutional isomer: They are also known as structural isomers. They have same molecular formula, but the bonding of groups is different. For example, n-pentane and isopentane.
