There are three different possible structures (known as isomers) of a dibromoethene molecule, c 2 h 2 br 2 c2h2br2 . one of them has no net dipole moment, but the other two do. draw lewis structures for each of these structures. include h h atoms. nonpolar c 2 h 2 br 2 c2h2br2 structure (one structure)

The structures are shown below

Explanation:

The Lewis structure is done with the elements represented by its letter signal, and the bonds between the atoms, representing the free pairs of electrons. At C₂H₂Br₂, there is a double bond between carbons, and each carbon can be bond to hydrogen or brome. The only brome has lone pairs because it's in group 7, so it has 3 lone pairs.

The three possible structure is shown below. Only the third is nonpolar because the dipole moments are canceled.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
