Question

what are the main postulates of VSEPR theory?

Answer 1

Process of VSEPR theory valence shell electron pair repulsion(VSEPR) theory is a model used to predict the geometry of individual molecules from the number of Electron pair surrounding their central atom...hope it will help uh....

Answer 2

$\Huge\green{{\mathcal{MAIN\: POSTULATES\: ARE :-}}}$

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

➨ Pairs of electrons in the valence shell repel one another since their electron clouds are negatively charged.

➨ A multiple bond is treated as if it is a single electron pair and the two or three electron pairs of a multiple Bond are treated as a single super pair.

➨ Where two or more resonance structures can represent a molecule, the vsepr model is applicable to any such structure .

➨ The valence shell is taken as a sphere with the electron pairs localising on the spherical surface at maximum distance from one another .
