Question

answer the questions in the table below about the shape of the sulfur hexabromide (sbr6) molecule. how many electron groups are around the central sulfur atom? note: one \electron group\ means one lone pair, one single bond, one double bond, or one triple bond. what phrase best describes the arrangement of these electron groups around the central sulfur atom? (you may need to use the scrollbar to see all the choices.)

Explanation:

Step1: Analyze bonding in $SBr_6$

Sulfur (S) is the central atom and is bonded to 6 bromine (Br) atoms. There are no lone - pairs on the sulfur atom. Each S - Br bond is a single bond. So the number of electron groups is the number of bonds.

Step2: Determine electron - group count

Since there are 6 S - Br single bonds around the sulfur atom, the number of electron groups is 6.

Step3: Identify electron - group arrangement

For a central atom with 6 electron groups and no lone - pairs, the electron - group arrangement is octahedral.

Answer:

How many electron groups are around the central sulfur atom? 6
What phrase best describes the arrangement of these electron groups around the central sulfur atom? Octahedral
