SF4 (with 1 lone pair on S) has molecular geometry:
- Acheck_circle
See-saw
- B
Tetrahedral
- C
Square planar
- D
Trigonal bipyramidal
Explanation
Five electron domains (4 bonds + 1 lone pair) give trigonal bipyramidal electron geometry; the lone pair occupies an equatorial position, making the molecular shape see-saw.
