Draw the Lewis structure of (AsF4) Use this stnicture; conjunction with VSEPR theory, predict: a)The electron domain geometry of the molecule: b)The molecular geometry (shape ofthe molecule). c)The bond angles around the centra atom. d)The polarity of the molecule. e) The type of hybridization f the central Hom.

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.
