The F - B r - F bond angles in B r F 5 and the C l - P - C l bond angles in P C l 5 , respectively, are

Options

  1. Aidentical in B r F 5 but non-identical in P C l 5
  2. Bidentical in B r F 5 and identical in P C l 5
  3. Cnon-identical in B r F 5 but identical in P C l 5
  4. Dnon-identical in B r F 5 and non-identical in P C l 5

Correct answer

D. non-identical in B r F 5 and non-identical in P C l 5

Step-by-step solution

The geometry of B r F 5 is square pyramidal. Here, the lone pair occupies the axial position and hence axial bonds will suffer more repulsion than equatorial bonds. Thus, the axial Br - F bond length will be different from equatorial Br - F . The geometry of P C l 5 is triangular pyramidal. The axial bonds suffer more repulsions than equatorial bonds, so they are larger in bond length.
