Chapter 7.SE, Problem 43AP

Interpretation Introduction

Interpretation:

The structure and name of six alkene isomers (including E,Z isomers) with molecular formula C₅H₁₀.

Concept introduction:

Structural isomers are compounds that have same molecular formula but different structural formula. Stereoisomers have same molecular and structural formula but they differ only in the arrangement of groups.

For naming alkenes, the longest carbon chain containing the double bond is to be chosen. Based on the name of the parent compound–the alkene name ends with the suffix–ene. The chain is to be numbered from the end that gives the lowest number to the carbon in double bond. Substituents are to be numbered according to their positions in the chain and listed alphabetically. The position of the double bond is indicated by giving the number of the first alkene carbon before the name of the parent name. The isomer that has the higher ranked groups on each carbon are on the same side of the double bond is said to have Z configuration. If the higher ranked groups are on opposite sides, the alkene is said to have E configuration.

To draw:

The structure and name six alkene isomers (including E, Z isomers) with molecular formula C₅H₁₀.
