Chapter 23.5, Problem 23.8E

Interpretation Introduction

Interpretation:

IUPAC names has to be given for the geometric isomers of the given compound.

Concept Introduction:

Geometric isomers are the isomers of same compound which differ in the relative positions the atoms occupy in space.  For alkene geometric isomers are possible if the carbon atoms in the end of the double bond are not bonded to same groups or atoms.  Usually trans isomer is more stable than cis isomer as the steric hindrance will be very less.

Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word.

Prefix represents the substituent present in the molecule and its position in the root name.

Suffix denotes the presence of functional group if any in the molecule.  It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc.

Root word represents the longest continuous carbon skeleton of the organic molecule.

If the compound has a unsaturated bond present in it, then the position of the unsaturated bond is mentioned in the IUPAC name itself.

To Give: The IUPAC name for the geometric isomers.
