Question
Chapter 7, Problem 8CTQ
(a)
Interpretation Introduction
Interpretation:
The relationship of given compound with the compound in Figure 7.3 should be stated.
Concept Introduction:
The compounds that have same molecular formula but have different arrangement of atoms in a space are known as isomers.
Conformers are obtained by the interconvertion of a molecule without breaking the bond through the rotation about a single bond. Consitutional isomers have same molecule formula but have different connectivity of atoms. The compounds that have same molecular formula and also have the connectivity of atoms but cannot be converted into one another by rotation about a single bond are known as configuratiol stereoisomers.
(b)
Interpretation Introduction
Interpretation:
The purpose behind to dermine the name of each molecule before to identify reactionship of each molecule with cis-1,2-dimethylcyclohexane should be predicted.
