plzz guys help me i want to know about ' valence shell electrons pair repulsion theory' ???
Answers
Hii...frnds...
~~~~~~~~~~~~
here is ur answer
~~~~~~~~~~~~
=> Electron pair present on given atom tend to remain at maximum distance from to remain at maximum distance from one another due to repulsion and attain most stable configuration. this stable configuration of molecule is known as it's geometry.
The order of repulsion is as following
LP-LP > LP-BP > BP- BP
DB-DB > DB-SB > SB- SB
SB- Single bond
DB - Double bond
LP - Lone pair
BP - Bpnd Pair.

Answer:
Valence Shell Electron pair repulsion : -
(1) Sidgwick and Powell proposed valence shell electron pair repulsion theory to predict the shapes of covalent molecules
(2) It is based on idea that the electron pairs on the atoms in a molecule repel each other
(3) The atoms in a molecule arrange themselves in such a way that repulsion is minimised.
(1) The arrangement of electrons is called electron pair geometry
