What atomic or hybrid orbital on sb makes up the sigma bond between sb and f in antimony(iii) fluoride, sbf3?
Afina-wow [57]

Answer: The four sp^3 hybridized orbitals on Sb makes up the sigma bonds between Sb and F in antimony(iii) fluoride ,SbF_3

Explanation:

According to VESPR theory:

Number of electrons around the central atom : \frac{1}{2}[V+N-C+A]

V = number of valence electrons

N = number of neighboring atoms

C = charge on cation

A = charge on an anion

In antimony(III) fluoride ,

Antimony being central atom: V= 5,N =3,C=0,A=0

Number of electrons : \frac{1}{2}[V+N-C+A]=4

Number of electrons around the central atom are 4 which means that SbF_3 molecule has four sp^3 hybridized orbitals.
