Which of the following is/are main postulates of VSEPR theory?

NCERT (Part-I) Page No. 113.

• The shape of a molecule depends upon the number of valence shell electron pairs (bonded or nonbonded) around the central atom. 

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

• These pairs of electrons tend to occupy such positions in space that minimise repulsion and thus maximise distance between them.

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

 • 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.
