What is the electron geometry and molecular geometry of teo2

Answer : The electron geometry and molecular geometry of the molecule is trigonal planar and bent or angular.

Explanation :

Formula used  :

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

Now we have to determine the hybridization of the given molecules.

The given molecule is,

The number of electron pair are 3 that means the hybridization will be and the electronic geometry of the molecule will be trigonal planar.

But as there are 2 atoms around the central phosphorous atom, the third position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be bent or angular.

Thus, the electron geometry and molecular geometry of the molecule is trigonal planar and bent or angular.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.
