Question

Explain the VSEPR principle with example ?
​

Answer 1

Answer:

VSEPR theory therefore views repulsion by the lone pair to be greater than the repulsion by a bonding pair. ... For example, the H2O molecule has four electron pairs in its valence shell: two lone pairs and two bond pairs. The four electron pairs are spread so as to point roughly towards the apices of a tetrahedron.

Answer 2

Explanation:

The VSEPR theory assumes that each atom in a molecule will achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom.
