The possible isomers of dibromoethene have to be drawn and the net dipole moment has to be indicated. Concept Introduction: ISOMERS: The molecules which have the same molecular formula but different arrangement of atom are called as isomers. There are two types of isomers, Structural isomers Stereo isomers Stereo isomers: Stereo isomers are the isomers that have same molecular formula but differ in spatial arrangement of atoms. Stereo isomers can be sub divided into two groups Optical isomers Geometric isomers Optical isomers: Optical isomers are the mirror image of a molecule and they can be rotated by plane polarized light. Geometric isomers: If there is restricted rotation in a molecule there arises geometric isomerism. Geometric isomers are also known as Cis- Trans isomerism. If the two atoms locked in same side of the molecule then it is called as cis isomers. If the two atoms locked in opposite side of the molecule then it is called as trans isomers.

Chapter 9, Problem 9.74P

Interpretation Introduction

Interpretation:

The possible isomers of dibromoethene have to be drawn and the net dipole moment has to be indicated.

Concept Introduction:

ISOMERS:

The molecules which have the same molecular formula but different arrangement of atom are called as isomers. There are two types of isomers,

Structural isomers

Stereo isomers

Stereo isomers:

Stereo isomers are the isomers that have same molecular formula but differ in spatial arrangement of atoms. Stereo isomers can be sub divided into two groups

Optical isomers

Geometric isomers

Optical isomers:

Optical isomers are the mirror image of a molecule and they can be rotated by plane polarized light.

Geometric isomers:

If there is restricted rotation in a molecule there arises geometric isomerism. Geometric isomers are also known as Cis- Trans isomerism.

If the two atoms locked in same side of the molecule then it is called as cis isomers.

If the two atoms locked in opposite side of the molecule then it is called as trans isomers.
