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 equal to the number of bonds.

Step2: Determine number of electron groups

Since there are 6 S - Br single bonds and no lone - pairs on sulfur, the number of electron groups around the central sulfur atom is 6.

Step3: Identify electron - group arrangement

According to the VSEPR (Valence - Shell Electron - Pair Repulsion) theory, when there are 6 electron groups around a central atom with 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
