C2br2 Lewis Structure - How To Discuss

C2br2 Lewis Structure

Need help drawing Lewis structures? 3

a) XeOF4

Here, I have 4F single bonds and 1 double bond, all associated with Xe. I don't know if it's xenon charge because it's a light gas and it has 6 connections in my structure instead of 8 ...

b) C2Br2

What is the central atom?

Thanks for helping me :)

XeOF4 looks right. The trick is to take the total number of valence electrons and subtract the number of electrons that bind to other elements and the number of electrons that bind nothing. In this case, xenon has 8 valence electrons, so the calculation is 862 = 0. In fact, 4 electrons bind fluorine and 2 electrons bind oxygen (double bond). 0 is exactly what you want because it is stable around Xe and indicates no load.

Bromine C2Br2 will be the central atom. The most important atom is almost always the central atom. The obvious exception is when you have a sugar or IC compound and carbon can be the central atom. In this case, I think carbon has triple bonds and each has the same bond with bromine, resulting in 3 sigma bonds and 2 pie bonds.
