Consider the following statements, 1. The shape of a molecule depends upon the number of valence shell electron pairs (bonded or non-bonded) around the central atom. 2. Pairs of electrons in the valence shell repel one another since their electron clouds are negatively charged. 3. These pairs of electrons tend to occupy such positions in space that minimize repulsion and thus maximise distance between them. 4. The valence shell is taken as a sphere with the electron pairs localizing on the spherical surface at maximum distance from one another. 5. 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. 6. Where two or more resonance structures can represent a molecule, the VSEPR model is applicable to any such structure. Which of the above statements are the postulates of VSEPR theory? Choose the correct option.
