Molecular Shapes

Molecular Shapes. Covalent Molecules. Determining Molecular Shapes. Lewis Structures only show us the 2-Dimensional shapes. Not the 3-D molecules we see in the real world This 3-D shape is important in determining the chemical and physical properties of a molecule.

Molecular Geometry – Shapes!

Molecular Geometry – Shapes!. Why does shape matter?. Properties of molecules depend on: Types of atoms present Arrangement around the central atom Polarity of Molecule is also determined by shape Polarity will affect the interaction between molecules. VSEPR Theory.

MOLECULAR SHAPES

MOLECULAR SHAPES In 1940 Sidgwick proposed an explanation of the shapes of molecules based on Lewis's model of molecular shape. He assumed Lewis's assumption that electrons tend to group in pairs.

Molecular Shapes

Molecular Shapes. Molecular Shapes. In order to predict molecular shape, we assume the valence electrons repel each other. Therefore, the molecule adopts whichever 3D geometry minimized this repulsion. We call this process V alence S hell E lectron P air R epulsion ( VSEPR ) theory.

Molecular Shapes

Molecular Shapes. Mr. Shields Regents Chemistry U10 L04. Molecular Shapes. When considering molecular shapes three things must be considered: 1) What kind of bonds are present? 2) How many bonds are there? 3) are there any lone pairs present?

Molecular Shapes – VSEPR Theory

Molecular Shapes – VSEPR Theory. The more you study chemistry, the more you will come to appreciate that it’s all about the electron. You have probably already learned that when two atoms form a covalent bond, they are in essence sharing a pair of electrons.
