Question

The molecular geometry of SF₆ is octahedral. What is the geometry of SF₄ (including lone pair(s) of electrons, if (any)?

(1) Square planar 

(2) Trigonal bipyramidal

(3) Tetrahedral 

(4) Pyramidal

Comments

Trigonal Biopyramidal

Answer 1

Ans. (2) Trigonal bipyramidal

Sol. SF₄ $\implies$ Steric No = 5 so hybridisation is sp³d.

Geometry is trigonal bipyramidal but shape is “See Saw”.

Answer 2

ANSWER IS (2)
