Identify the hybridisation and geometry of $\mathrm{SF}_4$ molecule respectively.

Identify the hybridisation and geometry of $\mathrm{SF}_4$ molecule respectively.
  1. $\mathrm{sp}_3^3$ and tetrahedral
  2. $\mathrm{sp}_3^3$ and trigonal bipyramidal
  3. $\mathrm{sp}^3 \mathrm{~d}^2$ and trigonal bipyramidal
  4. $\mathrm{sp}^3 \mathrm{~d}$ and seesaw

Solution

- Concept: $S F_4$ has a seesaw shape, which corresponds to $s p^3 d$ hybridization due to the presence of one lone pair and four bond pairs around the sulfur atom.
Answer: $s p^3 d$ and seesaw (Trigonal bipyramidal class with asymmetric distribution due to lone pair).
