Question

The shapes of $I{F}_3$ and $I{F}_7$ are respectively:

• A. square pyramidal and pentagonal bipyramidal
• B. octahedral and pyramidal
• C. trigonal bipyramidal and square antiprismatic
• D. distorted square planar and distorted octahedral

Answer 1

The correct option is A square pyramidal and pentagonal bipyramidal

As refer to IMAGE $01$

$I\to 5s^{2}5p^5$

at ground state.

For $I{F}_3$;

$I$ at excited state.

Geometry is Trigonal bipyramidal as refer to IMAGE $02$

As refer to IMAGE $03$

For $I{F}_7$,

$I$ at excited state is $s{p}^3{d}^3$

Geometry $=$ Pentagonal bipyramidal

Shape $=$ Pentagonal bipyramidal as refer to IMAGE $04$
