There are three different possible isomers of a dibromoethene molecule, c2h2br2c2h2br2 . one of them has no net dipole moment, but the other two do. draw lewis structures for each of these isomers. include hh atoms. nonpolar c2h2br2c2h2br2 isomer (one isomer)

Answers are in the explanation

Explanation:

In chemistry, isomers are substance with identical formulas (In this case C₂H₂Br₂) but different structures.

The three different structures are presented in the image.

Vectors represent the dipole moment. For a, vector will be cancel, that means this is the structure that has no dipole moment. In b and c the sum of the vector gives an up vector and a left vector, respectively. b and c have dipole moment.

I hope it helps!
