Question

for the Ion I3^- ,

1) draw a lewis structure.

2) state the geometry of molecule (if it has more than one central atom, give each central atom's geometry.

3) State which hybrid orbitals would be expected for the central atom(s).

4) give the approximate(ideal) bond angle(s) for the central atom(s).

5) state if its polar or non-polar.

A typed answer is prefered.

Answer 1

for I ion 1.) Lewis structure In the Lewis structure of Isr, there are three molecules of iodine along with extra electron which gims it negative charge to the total number of Valence electrons are 7x3 +1 = 22 e's. T:1-'1—1:17 2.) Geometry of molecular Electron pair geometry: Trigonal bipyra Molecular geometry: Linear. 3.) Hybridisation for central atom. - Hybridisation for central atomis spad 4) Bond angles for central atom. 180° - 5) polar or mon.polari Is ion is non-polar.
