The shape/structure of XeF 5 - and XeO 3 F 2 , respectively are :

Options

Apentagonal planar and trigonal bipyramidal
Boctahedral and square pyramidal
Ctrigonal bipyramidal and pentagonal planar
Dtrigonal bipyramidal and trigonal bipyramidal

Correct answer

A. pentagonal planar and trigonal bipyramidal

Step-by-step solution

(i) XeF 5 - St. No. = ( 5 + 2 ) = 7 so hybridisation is = sp 3 d 3 and structure is pentagonal planar. (ii) XeO 3 F 2    St. No. = 5 so hybridisation is = sp 3 d and structure is trigonal bipyramidal.
