Question

give the formula and describe the structure of a noble gas species which is isostructural with IF5-
​

Answer 1

Answer:

XeF

4

is isostructural with ICl

4

−

. It is square planar due to sp

3

d

2

hybridization which results in octahedral geometry with two lone pairs occupy opposite positions.

(ii) XeF

2

is isostructural with IBr

2

−

. It has a linear shape due to sp

3

d hybridization which results in trigonal bipyramidal geometry with 3 lone pairs in equatorial plane.

(iii) XeO

3

is isostructural with BrO

3

−

. It has a pyramidal shape due to sp

3

hybridisation with terahedral geometry in which one position is occupied by a lone pair.

Hope it's will help you

Answer 2

Answer:

(a) ICl4– (b) IBr2– (c) BrO3–

(a) ICI4– —XeF4 (Square planar)

(b) IBr2– —XeF2(pyramidal)

(c) BrO3– — XeO3 (Linear)
