Square Pyramidal Molecular Geometry/Shape and Bond Angles

Описание: In this video we’ll look at the Square Pyramidal Molecular Geometry and Bond Angles. We'll use the example of ClF5 to understand the molecular shape. To do that we'll use VSEPR Theory and the Lewis Structure for ClF5 and then use interactive models and visualization to visualize the Square Pyramidal geometry.

The Square Pyramidal molecular shape occurs when there are five atoms attached to the central atom and one lone pair (unbonded pair) of electrons on the central atom. ClF5 is a good example of a Square Pyramidal molecular geometry.

It is useful to understand the generic molecular geometry and then apply it to specific molecules using either the steric number and number of lone pairs of electrons or the AXE notation.

For the more on the molecular geometries below see my video at:

Linear
Bent (90 and 120-degree bond angles)
Trigonal Planer
Trigonal Pyramidal
Tetrahedral
Trigonal Bipyramidal
Octahedral

The role of lone pairs (unbonded electron pairs) and their VSEPR influence on molecule shape will also be addressed in the video.
