Hybridization
This is process in which atomic orbitals are mixed to
form new identical hybrid orbitals.
Procedure for determining hybridized orbitals.
1. Draw the Lewis Diagram for the molecule.
2. Determine the Stearic Number, which are the
groups around the central atom. (A group is another
atom sharing electrons or a lone pair).
3. 2 = sp
Linear shape
3= sp2
Trigonal Planar
4 = sp3
Tetrahedral
5 = dsp3
Trigonal bipyramidal
6 = d2sp3 Octahedral
What is the hybridization around the central atom of
the following compounds?
BF3
CF4
SO2
CO2
PCl5
Sigma and Pi bondsSigma bond-electrons in an end to end overlapping
regions to share.
Pi bond- electrons in a parallel overlapping region to
share.
Single bonds consist of a sigma bond
Double bonds consist of a sigma and pi bond
Triple bonds consist of a sigma and two pi bonds.
