Question

Explain valence shell electron pair repulsion theory?​

Answer 1

Answer:

Valence Shell Electron Pair Repulsion Theory (VSEPR) is a molecular model to predict the geometry of the atoms making up a molecule where the electrostatic forces between a molecule's valence electrons are minimized around a central atom

Explain valence shell electron pair repulsion theory_??

$\huge\black{\mid{\fbox{\tt{ANSWER}}\mid}}$

Lewis concept is unable to explain the shapes of molecules but VSEPR theory provides a simple method to predict the shapes of covalent molecules. This theory, was developed earlier by Sidgwick and Powell in 1940, and it was further improved by Gillespie and Nyholm in (1957).

The theory is primarily based upon the fact that in a polyatomic molecule the direction of bonds around the central atom depends upon the total number of electron pairs (bonding as well as non bonding) in its valence shell. These electron pairs place themselves as far apart as possible in space so as to have minimum repulsive interaction between them. The minimum repulsions correspond to the state of minimum energy and maximum stability of the molecule.
