Trigonal Bipyramidal

[905085650]

Can someone explain to me the bond angles in a trigonal bipyramidal shape? (Phosphorous pentachloride for example)

[whitney_2C]

The bond angles in trigonal bipyramidal are 180 degrees, 90 degrees, and 120 degrees. The 180 degrees refers to the bond angle between the axial atoms, the 90 degrees refers to the bond angles between an axial atom and an equatorial atom, and the bond angle 120 degrees refers to that between the equitorial atoms.

I find it helpful to look at photos of molecules to understand their shapes, so I hope this helps!

Trigonal Bipyramidal is like a totally blended version of linear, axial, and trigonal planar, equatorial.
