MCQ
Which of the following is planar ?
- ✓$XeF_4$
- B$XeO_4$
- C$XeO_2F_2$
- D$XeOF_4$
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.

$(I)$ they exhibit high enthalpies of atomisation as the $d-$ subshell is full
$(II)$ $zn$ and $Cd$ do not show variable oxidation states while $Hg$ shows $+ I$ and $+ II$
$(III)$ Compound of $Zn,\,Cd$ and $Hg$, are paramagnetic in nature
$(IV)$ $Zn,\,Cd$ and $Hg$ are called soft metals
