Question
What is the molecular geometry of 
?
What is the molecular geometry of 
Answer
There are six electron domains in 
. 
has five bonding and one nonbonding pairs of electrons. The electron domain geometry of 
is octahedral. When a molecule has octahedral electron domain geometry and has five bonding and one nonbonding pairs, the molecular geometry is square pyramidal.
