VSEPR determining shape

Postby JulieAljamal1E » Sun Nov 11, 2018 2:14 pm

How do you figure out the shape of a compound? Is it just based off of the number of bonding pairs on the central atom?

Draw the Lewis structure, this will help you determine the shape.

To determine, the shape (molecular geometry) of a molecule, you would have to consider the number of electron groups which comprises of both bonding pairs and lone pairs.

To figure out the shape, model out the Lewis dot structure of the molecule, figure out the number of bonding pairs and lone pairs around the main/central atom, use VSEPR to figure out the electron pair shape of the molecule and the VSEPR shape to then figure out the angles between that are found between each of the bonding pairs.
