SBr2 Lewis Structure – How to Draw the Dot Structure for SBr2 (Sulfur dibromide)


Hi, this is Dr. B. Let’s do the Lewis structure
for SBr2: sulfur dibromide. On the periodic table, Sulfur is in group 6, sometimes called
16; and Bromine is in group 7, sometimes called 17. We have two Bromines, though, so let’s
multiply that times 2. Six plus 14 is 20. So we have 20 valence electrons. We’ll put
Sulfur in the middle because it’s the least electronegative and then we’ll put Bromine
on either side. So there we have our structural, kind of skeleton formula. What we want to
do is, put some valence electrons–20 valence electrons around the molecule. Let’s start
out by putting them between the atoms, form a chemical bond. We’ve used 4. And then on
the outside, 6, 8, 10, 12, 14, 16; and on the inside, 18, 20. We’ve used all 20 valence
electrons. Let’s see how we do with our octet. This Bromine has 8, and this Bromine has 8,
so those outer shells are full. In the center, Sulfur has 8 as well, and we’ve used 20 valence
electrons. So that’s the Lewis structure for SBr2. If we wanted to draw a structural formula
we could draw it like this right here. And that’s it. This is Dr. B., and thanks for
watching.

  1. In general atoms in Group 7A (sometimes called 17) don't form double or triple bonds.

    The other reason is that the formal charges would be +2 for each Bromine. We want our formal charges to be as close to zero as possible. As shown in the video the formal charges for each atom is zero.

  2. I have a problem, I need to know how to make the lewis structure for Cd I2 and I don't know how to use the non metal category of the periodic table please help thank you
