Are all the five bonds in `"PCl"_(5)` molecule equivalent ? Justify your answer.

Text Solution

Verified by Experts

`PC_(5)` has trigonal bipyramid structure. It has three equatorial bonds inclined at angle of 1200 and two axial bonds inclined at angle of `90^(@)`. As a result, axial bond pairs suffer greater repulsion than equatorial bond pairs. Consequently, axial bonds are longer (240 pm) as compared to equatorial bonds (202 pm). Thus, all the five P C bonds in `PCl_(5)` are not equivalent.
