Question

Postulates of VESPER

Answer 1

Answer:

Postulates of VSEPER Theory:

The total number of valence shell electron pairs decides the shape of the molecule. The electron pairs have a tendency to orient themselves in a way that minimizes the electron-electron repulsion between them and maximizes the distance between them.

Explanation:

Answer 2

THE POSTULATES OF VSEPR THEORY IS THAT THE SHAPE OF A MOLECULE IS DECIDED BY THE LONE PAIRS AND BOND PAIRS. THE REPULSIONS IN L.P-L.P > L.P-B.P > B.P-B.P.

Explanation:

• The VALENCE ELECTRON PAIR REPULSION THEORY states that the central metal atom is surrounded by the side atoms.
• The electron pairs arrange themselves in such a position that the repulsion is minimum and the stability is maximum.
• If along with bond pairs, lone pairs are present then the shape of the molecule gets distorted.
• The repulsions is in the order: lone pair-lone pair> lone pair-bond pair> bond pair- bond pair.
• The molecule having sp hybridization is linear, sp2 id trigonal planar, sp3 is tetrahedral, sp3d is trigonal bipyramidal, sp3d2 is octahedral.
