Question

Rule of VSEPR................... ​

Answer 1

$\huge\bold\purple{Answer:-}$

1. Electron pairs arrange themselves in such a way that repulsion between them is minimum.

2. The molecule acquires minimum energy and maximum stability.

3. Lone pair of electrons also contribute in determining the shape of the molecule.

4. Repulsion of other electron pairs by the lone pair (L.P) stronger than that of bonding pair (B.P)

Trend for repulsion between electron pair is L.P - L.P> LP-B.P> B.P - B.P

Lone pair -Lone pair repulsion is maximum because this electron pair is under the influence of only one nucleus while the bonded pair is shared between two nuclei. Thus the number of lone pair and bonded pair of electrons decide the shape of the molecules. Molecules having no lone pair of electrons have a regular geometry

Answer 2

Answer:

According to VSEPR theory it states that the atomic sttucture of an element bonding is based on the valence and valence shell .
