MCQ
Which of the following is planar ?
- ✓$XeF_4$
- B$XeO_4$
- C$XeO_2F_2$
- D$XeOF_4$
✓
Answer
Correct option: A.
$XeF_4$
a
In $Xe F_4$ molecule, central atom $Xe$ has $6$ electron pairs around it in which $4$ electron pairs are bonding pairs and $2$ electron pairs are lone pairs.
In $Xe F_4$ molecule, central atom $Xe$ has $6$ electron pairs around it in which $4$ electron pairs are bonding pairs and $2$ electron pairs are lone pairs.
As $6$ electron pairs are three $Xe F_4$ structure should be octahedral but it square planar due to two lone pairs on it.
Because of two lone pairs repulsions increases and shape becomes square planar.
