Question

The shape/structure of [XeF₅]^– and XeO₃F₂, respectively are :

(1) octahedral and square pyramidal 

(2) trigonal bipyramidal and trigonal bipyramidal

(3) trigonal bipyramidal and pentagonal 

(4) pentagonal planar and trigonal bipyramidal

Answer 1

Ans. (4) pentagonal planar and trigonal bipyramidal

Sol. (i) XeF₅^–

St. No. = (5 + 2) = 7

so hybridisation is = sp³d³ and structure is pentagonal planar.

(ii) XeO₃F₂

St. No. = 5

so hybridisation is = sp³d and structure is trigonal bipyramidal.
