What is the molecular geometry for teo2?

This molecule is Trigonal planar Because it has 3 e- pairs around the central atom, 3 atoms bonded to it, and 0 lone pairs.

Chemical properties

TeO₂ Is barely soluble in water and soluble in strong acids and alkali metal hydroxides. It is an amphoteric substance And therefore can act both as an acid or as a base depending on the solution it is in. It reacts with acids to make tellurium salts and bases to make tellurites.

1 Answer. The oxidation state of Te in TeO₂ Is + 4.

Ingestion: Poison by ingestion. May cause dry mouth, suppression of sweat, garlic odor to breath and urine. Skin: May cause irritation and itching. Eye: May cause irritation.

Tellurate

TeO3 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Te6+ is bonded to six equivalent O2- atoms to form corner-sharing TeO6 octahedra. The corner-sharing octahedral tilt angles are 41°.

D.) Trigonal planar. Hint: In water molecules there are two lone pairs on oxygen. According to VSEPR theory, there are repulsions of lone pair-lone pair repulsions, the water molecule tends to acquire bent shape or V-shape.

Polarity of water molecules

A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because The oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons.

Solution : TeO (oxidation number of Te is +2) is basic <br> `TeO_(2)` (oxidation number of Te is +4) is amphoteric <br> `TeO_(3)` (oxidation number of Te is + 6) is acidic. <br> As the oxidation number of the element forming oxide increases, the acidic nature also increases.

There are many transition metals (like copper, zinc and iron) which form amphoteric oxides. Chemical nature of oxide will be determined by the oxidation state of the central metal ion of oxide.

Tellurium is soluble in sulfuric acid, nitric acid, potassium hydroxide and potassium cyanide solution. It is Insoluble in water.

Solution : The stability of `+4` oxidation state increases from `SO_(2) ” to ” TeO_(2)` Because of inert pair effect. Therfore, reducing character decreases.

I SO2 is reducing agent as sulphur has d-orbital so it can easily expand its + 4 oxidation state to f 6 oxidation state and acts as reducing agent while in Te oxidation number changes from O to + 4 and electrons are reluctant to take part in bond formation due to poor shielding of d- and f -orbital.

I) Sulphur dioxide is reducing agent Because sulphur has d-orbital so it can easily expand its oxidation state +4 to +6 and thus behave as reducing agent. in the case of TeO₂, Te is a heavier element and due to inert pair effect, the Te does expand its oxidation state +4 to +6.

Lewis structure of SF4 Contains four single bonds between the Sulfur (S) atom and each Fluorine (F) atom. The Sulfur atom (S) is at the center and it is surrounded by 4 Fluorine atoms (F). The Sulfur atom has 1 lone pair while all the four fluorine atoms have 3 lone pairs.
