In PCl_(5), phosphorus is in sp^(3)d hybridised state but all its five bonds are not equivalent. Justify your answer with reason. |
| Answer» Solution :`PCl_(5)` has trigonal bipyramid geometry. It has three equatorial and two axial bonds. Since each axial P-Cl bond is repelled by three bond pairs and each equatorial P-Ci bond is repelled by only two bond pairs, therefore, axial bonds are longer (240 PM) than equatorial bonds (202 pm) than equatorial bonds (202 pm). Thus, all the five P-Cl bonds in `PCl_(5)` are NT equivalent. | |
