Question

5. According to Valence Shell Electron
Pair Repulsion Theory, the shape of
Phosphorus Pentachloride (PC15) is​

Answer 1

Answer:

Let us first see the lewis dot structure of PCl5

Now, the according to the VSEPR theory a molecule having 5 bond pairs is said to be having a trigonal bipyramidal shape. Hence, this is the shape of PCl5.

If you look at the 3D structure of PCl5, you will observe this:

If you notice the 3 atoms namely the Cl-P-Cl arranged linearly in the middle, these 2 chlorine atoms are called the axial atoms whereas if you notice the other 3 chlorine atoms arranged along the x axis in a trigonal planar shape, these Cl atoms are the equatorial atoms.

The angle between an axial and an equatorial atom is 90 °. Which makes the angle between the two axial atoms to be 180°. The angle between 2 equatorial atoms is 120°.
