What is the electronic geometry about a central atom which has five regions of electron density?

The electron geometry about a central atom that has five regions of electron density is trigonal bipyramidal. This is one of the common geometries

What is the electronic geometry on a central atom water?

Water has 4 regions of electron density around the central oxygen atom (2 bonds and 2 lone pairs). These are arranged in a tetrahedral shape. The resulting molecular shape is bent with an H-O-H angle of 104.5°.

What are the 5 Vsepr shapes?

The VSEPR theory describes five main shapes of simple molecules: linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.

What is the electron pair geometry for C in CH3?

In a CH3CH3 molecule, each C atom has four electron pairs arranged tetrahedrally. Within this molecule, each CH3 considered as a separate group has a trigonal pyramidal geometry (with three C—H bonding pairs and a fourth pair from the C—C bond around the C atom).

What is the molecular geometry around the central atom of methyl green?

Its electron geometry and its molecular geometry are both tetrahedral as in methane. This atom has three atoms directly attached and no lone pairs. Its electron geometry and its molecular geometry are both trigonal planar.

What is the electron geometry if you have 4 electron groups around the center atom?

4 electron pairs around a central atom adopt tetrahedral geometry.

What is electron pair geometry vs molecular geometry?

The main difference between electron geometry and molecular geometry is that electron geometry is found by taking both lone electron pairs and bonds in a molecule whereas molecular geometry is found using only the bonds present in the molecule.

What is electron pair geometry?

electron-pair geometry: arrangement around a central atom of all regions of electron density (bonds, lone pairs, or unpaired electrons) linear: shape in which two outside groups are placed on opposite sides of a central atom. molecular structure: structure that includes only the placement of the atoms in the molecule.

How many electron groups are on the central atom?

There are six electron groups around the central atom, each a bonding pair.

What determines the molecular geometry?

The shape of a molecule is determined by the location of the nuclei and its electrons. The electrons and the nuclei settle into positions that minimize repulsion and maximize attraction. Thus, the molecule’s shape reflects its equilibrium state in which it has the lowest possible energy in the system.
