Question

Draw the Lewis Dot-Dash Structure of the molecules and ions below. Indicate the AXE notation, a Lewis structure (or one of the possibilities), and the election andmolecular geometry.

1) NOH3
2) BrF5
3) Si2I4
4) PH4+
5) H2SO4

Answer 1

1)H H
I I

H - C - O - C - H

I I

H H

All Electrons are bonds Except for four. two of which Are above O and two of which are below.
2)**..
h-N-h is nh3
***|
***h

(ignore the asterisks)
3)

Answer 2

NOH3 AXE = AXA H- No 8: e structure electron geometry 3 tetrahedral Molecular geometry =) tetrahed net Lewis 2) Brfg AXE = AXGE electron geometry s octahedral Molecular geometry = Pentagonal pyramided . T). AXE =) Az Xa :7 – si = si-3: election geometry =) planner Molecular geometry =) planner

49 PM AXE = AXA elechon geometry = tetrahedrul IH- P - Molecular Geometry =) tetrahedral I - 5) H2 SO4 AXE =) A X4 Electron Geometry :) tetrahedral corecular Geometry =) te trained rul 40 § 9-4 : 0
