Answer: trigonal bipyramidal
Step-by-step explanation:
Number of electron pairs =
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
:
In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.
The number of electron pairs are 5 that means the hybridization will be
and geometry of the molecule will be trigonal bipyramidal.
