Question

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

Answer 1

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

Step-by-step explanation:

According to VESPR theory:

Number of electrons around the central atom :
`(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 :
`(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.
