MCQ
The structure of $\ce{IF_7}$ is :
  • A
    Square pyramidal.
  • B
    Trigonal bipyramidal.
  • C
    Octahedral.
  • ✓
    Pentagonal bipyramidal.
✓

Answer

Correct option: D.
Pentagonal bipyramidal.
$\text{IF}_7=\frac12(7+7)=7$
$\Rightarrow sp^3$
$d^3- $ hybridisation
$\Rightarrow$ Pentagonal bipyramidal
