The purpose of hybridization

Postby 005199750 » Fri Dec 07, 2018 8:37 pm

Why do we use hybridization to characterize molecules? How does it further our understanding of the molecule's shape? I would like to better understand how I can use hybridization as a tool for understanding chemistry.

Hybridization gives the correct number of bonds. For example, using atomic orbitals, CH4 could only form two bonds, but we know that carbon forms 4 bonds. When you use hybrid orbitals, there are four hybrid orbitals (sp^3), which allows carbon to form 4 bonds. Also, the bond angles are incorrect for atomic orbital theory. For example, using CH4, between the 3 p orbitals (px, py, px), the bond angle is 90 degrees, but we know that methane has a tetrahedral shape and thus, a bond angle of 109.5
