Identify the hybridisation and geometry of SF_4 molecule respectively.

MHT CET 2024 Chemistry question

Identify the hybridisation and geometry of molecule respectively.

(A) and tetrahedral
(B) and trigonal bipyramidalCorrect
(C) and trigonal bipyramidal
(D) and octahedral

Answer: (B)

Solution

In sulfur (group 16, 6 valence electrons) forms 4 S-F bonds and keeps 1 lone pair, so it has 5 electron pairs (steric number 5). Five electron pairs need one s, three p and one d orbital, i.e. hybridisation, and the electron-pair arrangement is trigonal bipyramidal (the lone pair sits in an equatorial
