VSEPR - valence shell electron pair repulsion theory

Hybridisation- e.g. Sp, Sp2, sp3, Sp3d2 etc

Hybridisation predicts regular geometries-- VSEPR has the advantage of predicting how bond angles may deviate from the regular geometries.

Greek mathematician known for his theories in geometry?

You're probably referring to Euclid, whose theories on geometry are still used today, hence "Euclidean Geometry". If it's not Euclid , Pythagoras was also quite well-known for maths, geometry and the like.

What is the vsepr model mainly used for?

The VSEPR (Valence Shell Electron Pair Repulsion) model is mainly used to predict the geometry of molecules based on the arrangement of electron pairs around the central atom. It helps to understand the spatial arrangement of atoms in a molecule and predict the bond angles between them.


What are the five different molecular geometries?

Molecular geometry is the name of the geometric shape used to describe the shape of a molecule. The five molecular geometries are linear, trigonal planar, bent, tetrahedral, trigonal pyramidal, and seesaw.


If a molecule has the general formula AX4 and has trigonal bipyramidal molecular geometry what bond hybridization is used by the central atom A?

It would be sp3d hybridised.


Are theories used to make predictions?

Yes, theories are used to make predictions by offering explanations of observed phenomena and providing frameworks for understanding how a system works. By using theories as a guiding framework, scientists can predict how a system will behave under certain conditions based on the principles outlined in the theory.

How do you determine the shape of molecules?

The shape of molecules is determined by the number of bonding and non-bonding electron pairs around the central atom. The VSEPR (Valence Shell Electron Pair Repulsion) theory is commonly used to predict molecular geometry based on electron pairs' repulsion. The arrangement of these electron pairs results in different molecular shapes such as linear, trigonal planar, tetrahedral, and more.


What is contribution of Euclid in geometry?

His major contributions are in geometry and in his book The Elements. He gave many rules of geometry which are also used nowadays. Books of Euclid provide a base of geometry. Euclid's ideas and theories are still considered as basics of mathematics. His most famous work was Metric. Another contribution of Euclid was that he gave the practical ideas in Mathematics.


Where is the geometry used?

Geometry is used mainly in construction.
