MCQ
Molecular shapes of $SF_4 , CF_4$ and $XeF_4$ are
  • A
    the same with $2, 0$ and $1$ lone pair of electrons respectively
  • B
    the same, with $1, 1$ and $1$ lone pair of electrons, respectively
  • C
    different, with $0,1$ and $2$ lone pair of electrons, respectively
  • ✓
    different with $1,0$ and $2$ lone pair of electrons, respectively
✓

Answer

Correct option: D.
different with $1,0$ and $2$ lone pair of electrons, respectively
d
Molecular shapes of $SF _4$ is square pyramid due to one lone pair of $S$. $CF _4$ has tetrahedral geometry and $XeF _4$ has square planar structure with two lone pair of $Xe.$
