Chapter 6, Problem 18E

(a)

Interpretation Introduction

Interpretation:

One constitutional isomer and all possible configurational isomers after labelling as Z or E needs to be determined.

Concept Introduction:

Constitutional isomer is these types of isomer where in the molecules have same molecular formula with different bonding patterns.

Configurational isomers are stereoisomers that have same molecular formula and same connectivity which cannot be converted through rotation about the single bond into another form.

(b)

Interpretation Introduction

Interpretation:

To generalize about all terminal double bonds in the structures in terms of Z or E.

Concept Introduction:

Terminal double bond indicates the double bond that is at the end of the chain of carbon atoms. At the end there are 2 H atoms that is substituted on carbon atom in double bond.

(c)

Interpretation Introduction

Interpretation:

The relation between compound III and IV

Concept Introduction:

When the isomer has same molecular formula and different structural formula namely their bonding pattern is different, then it is constitutional isomer.
