Question

VESPR theory ?
define it

Answer 1

THE MAIN THEORY OF VESPR
1. the shape of a molecule depends upon the number of valence shell electron pair around the central atom.
2. pairs of electrons in the valence cell repair one another since they are electron clouds are negatively affected.
3.this pairs of electrons tend to occupy search positions in the safe that minimise repulsion and does maximize distance between them.
4. the valence shell is taken as a sphere with the electron pairs localising on the spherical surface at the 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. what two or more resonance structure can be presented a molecule the Vespa model is applicable to any such structure.
