Questions 1 - 1

What is the molecular geometry of $\text{ClF}_5$ ?

Square pyramidal

Square planar

Octahedral

Trigonal pyramidal

Tetrahedral

Explanation

There are six electron domains in $\text{ClF}_5$ . $\text{ClF}_5$ has five bonding and one nonbonding pairs of electrons. The electron domain geometry of $\text{ClF}_5$ is octahedral. When a molecule has octahedral electron domain geometry and has five bonding and one nonbonding pairs, the molecular geometry is square pyramidal.
