$\huge\tt\colorbox{black}{\color{orchid}{Answer}}$

Main postulates of VSEPR theory :-

❤ The shape of a molecule depends upon the number of electron pairs in the valence shell of the central atom.

❤ Electron pair in the valence shell repel one another since their electron clouds are negatively charged.

❤ The electron pairs in the valence shell occupy their position in space around the central atom in a such a way that the distance between them is maximum and the molecule acquires a state of minimum energy and maximum stability.

❤ The repulsive interactions, of electron pairs decrease in the order

lone pair-lone pair > lone pair-bond pair > bond pair-bond pair

❤ The repulsion is maximum in the body when the angle is 90⁰ and minimum at 180⁰.

Answer 2

Answer:

-The shape of a molecule depends upon the number of electron pairs in the valence shell of the central atom.

-Electron pair in the valence shell repel one another since their electron clouds are negatively charged.

-The electron pairs in the valence shell occupy their position in space around the central atom in a such a way that the distance between them is maximum and the molecule acquires a state of minimum energy and maximum stability.

-The repulsive interactions, of electron pairs decrease in the order

lone pair-lone pair > lone pair-bond pair > bond pair-bond pair

- The repulsion is maximum in the body when the angle is 90⁰ and minimum at 180⁰.
