Question

Total number of hybrid and pure orbitals in PCI5and SF6
molecules are x and y, then (x+y) is
​

Answer 1

Answer:

Three P—Cl bond lie in one plane and make an angle of 120  

o

 with each other; these bonds are termed as equatorial bonds. The remaining two P—Cl bonds—one lying above and the other lying below the equatorial plane, make an angle of 90  

o

 with the plane. These bonds are called axial bonds. As the axial bond pairs suffer more repulsive interaction than the equatorial bond pairs, therefore axial bonds have been found to be slightly longer and hence slightly weaker than the equatorial bonds; which makes PCl

 molecule more reactive.
