Sagot :
(a) Electron domain geometry: TBP
(b) molecular geometry of the molecule: see-saw
(c) The bond angles around the central atom:
∠F-As-F (equatorial) : 120° and
∠F-As-F (axial): 90° but actually less than these values.
(d) This is a polar molecule.
(e) sp³d hybridization of the central metal atom.
What is Lewis structure?
A molecule's valence shell electrons are shown in a very simple manner via a Lewis structure. It is used to demonstrate how the electrons in a molecule are positioned around particular atoms.
It demonstrates the bonds that exist between a molecule's atoms and its lone pairs of electrons. When used in conjunction with hybrid orbitals, Lewis structures can also be helpful in predicting molecular geometry.
The Lewis structure of [AsF₄]⁻ is drawn below:
(a) The electron domain geometry of the molecule is: TBP (trigonal bipyramidal)
(b) The molecular geometry of the molecule: see-saw.
(c) The bond angles around the central atom:
Expected bond angle:
∠F-As-F (equatorial) : 120° and
∠F-As-F (axial): 90°
but it is observed that, it is less than the expected value due to l.p-b.p repulsion.
(d) This is a polar molecule.
(e) The type of hybridization of the central atom: sp³d.
