There are three different possible structures (known as isomers) of a dibromoethene molecule, C 2 H 2 Br 2 . One of them has no net dipole moment, but the other two do. Draw Lewis structures for each of these structures. Include H atoms.

Explanation:

Isomers is any of two or more compounds with the same molecular formula but with different structure.

Structural isomers or constitutional isomer are any of two or more compounds with same molecular formula but different bonding patterns and their atomic organisations (structure).

Make sure to use dots and not only sticks in your representation. Here is the analysis shown in the figure below;

there are two significant figures.
