Chapter 5.11, Problem 29PTS

(a)

Interpretation Introduction

Interpretation:

The configuration of double bond in the given alkene has to be assigned as either E or Z.

Concept Introduction:

Cistrans isomerism (or) geometric isomerism or configurational isomerism:

The two similar groups (or higher priority groups) are in same side in double bond of alkenes is called as cis isomer (or Z-isomer). Two similar groups (or higher priority groups) are opposite side in double bond of alkenes is called as trans isomer (or E-isomer).

Example:

Organic Chemistry, Chapter 5.11, Problem 29PTS , additional homework tip  1

E-Z designators are used as like cis-trans terminology for non-similar groups attached alkenes.

In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher molecular weight. If the higher priority groups are on the same sides, then the configuration is designated as Z. If the higher priority groups are on the opposite sides, then the configuration is designated as E.

E-Z designators are used as like cis-trans terminology for non-similar groups attached alkenes.

In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher molecular weight. If the higher priority groups are on the same sides, then the configuration is designated as Z. If the higher priority groups are on the opposite sides, then the configuration is designated as E.
