Question

state the contribution of nyholm and gillesppie VESPR in theory​

Answer 1

Explanation:

Ronald Gillespie is best known for his contribution along with Ronald Nyholm, in the development of Valence Shell Electron Pair Repulsion (VSEPR). The VSEPR is a set of rules that helps you to determine the geometric shape of a molecule, based on what molecule it is. He also helped to develop the LCP theory.

Answer 2

Gillespie has done extensive work on expanding the idea of the Valence Shell Electron Pair Repulsion (VSEPR) model of Molecular Geometry, which he developed with Ronald Nyholm (and thus is also known as the Gillespie-Nyholm theory), and setting the rules for assigning numbers.
