MCQ
The hybridisation of central iodine atom in $IF_5 , I_3^-$ and $I^+_3$ are respectively
- ✓$sp^3d^2 , sp^3d, sp^3$
- B$sp^3d, sp^3d, sp^3$
- C$sp^3d^2 , sp^3d^2 , sp^3$
- D$sp^3d, sp^3d^2 , sp^3$
✓
Answer
Correct option: A.
$sp^3d^2 , sp^3d, sp^3$
a
The comrect option is $(A)$
The comrect option is $(A)$
Explauation The hybridisation of If $_{5}$ molecule is $S p^{3} d^{2}$, as the ceutral atom ioduie has 7 valeuce electrons out of which 5 electuons foum 5 sigma bonds with $F$ atoms aud 2 electuons foum 1 lone Lone pair implying the hybrudisation of the ceutral atom is $s p^{3} d^{2}$
The hybruduiation of $I_{3}-$ is $S p^{3} d$. aud it has 3 lone pars aud 2 bond pajrs. If has linear shape
$I_{3}+$ has $\operatorname{sp}^{3}$ hybrudisation and two pairs on central atom, therefore shape would be beut
