Question

the image below represents a molecule that takes up a three - dimensional space. use this image to answer the question that follows. what does the net dipole moment of pf₅ look like? select the correct answer below: vector pointing toward f vector pointing toward p the dipole moment is 0 none of the above

Explanation:

Step1: Analyze molecular geometry

$PF_{5}$ has a trigonal - bipyramidal geometry.

Step2: Consider bond - dipole vectors

The three equatorial P - F bonds are at 120° to each other and their bond - dipole vectors cancel out. The two axial P - F bonds are in opposite directions and their bond - dipole vectors also cancel out.

Step3: Determine net dipole moment

Since all bond - dipole vectors cancel, the net dipole moment of $PF_{5}$ is 0.

Answer:

The dipole moment is 0
