Question

In the gaseous state, $PC{l}_5$ exists in the form of trigonal bipyramidal. In the structure, all the bonds are of equal length and can be treated equivalent. True or False?

• A. True
• B. False

Answer 1

The correct option is B

False

In the gaseous state, $PC{l}_5$ exists in the form of trigonal bipyramidal.

The equatorial bonds are shorter than the axial bonds. While the two axial bonds are 214 pm, the three equivalent equatorial bonds are 202 pm.

So the axial Chlorine atoms are more susceptible to be removed than the three equatorial ones!
