Question

i dont understand the lewis dot structure of SOBr2 can someone help?

Answer 1

The central atom is sulfur. There are 26 electrons to account for. Each bromine will have an octet, with three lone pairs. Sulfur has one lone pair, and oxygen has two lone pairs.

......Br
.......|
O = S :
.......|
..... Br

With a double bond between O and S, the formal charges have been minimized at zero for each element. For central atoms which are not in period 2, the minimizing of formal charge gives a more realistic picture of bond order than completing the octet. Therefore, this is a hypervalent molecule.

Your questions:
How many nonbonding electron pairs are on the oxygen atom? 2 lone pairs
How many nonbonding electron pairs are on the sulfur atom? 1 lone pair
How many nonbonding electron pairs are on each of the bromine atoms? 3 lone pairs
How many valence electrons are in the structure? There are 26 electrons
How many covalent bonds are in the structure? 3 covalent bonds: 2 single bonds and 2 double bond
What is the electronic geometry around the central sulfur atom? The electron pair geometry is tetrahedral
What is the molecular geometry around the central sulfur atom? The molecular geometry is trigonal pyramidal
