How To Determine Hybridization With Double Bonds. The easiest way to determine hybridization is to with the vsepr theory and determine the number of electron groups around your central atom. The carbons in alkenes and other atoms with a double bond are often sp 2 hybridized and have trigonal planar geometry.
When the carbon atom is bonded to four other atoms. Structure is based on trigonal planar geometry with one lone pair occupying a corner. The exponents on the subshells should add up to the number of bonds and lone pairs.

The Carbon Is Bonded To Two Other Atoms, That Means It Needs Two Hybrid Orbitals, Aka Sp.
In this video, we use both of these methods to determine the hybridizations of atoms in various organic molecules. The double and triple bonds found in molecules are actually a combination of bonds. Since iodine has a total of 5 bonds and 1 lone pair, the hybridization is sp3d2.
How Does Hybridization Relate To The Periodic Table?
All the carbon atoms in an alkane are sp 3 hybridized with tetrahedral geometry. Of lone pairs = 2 + 1 = 3. In other words, you only have to count the number of bonds or lone pairs of electrons around a central atom to determine its hybridization.
Review The Video Above (Start Of The Sp² Section) For An Overview Of Sp² And Sp Hybridization.
An easy way to figure out what hybridization an atom has is to just count the number of atoms bonded to it. Assign the hybridization and shape of molecule. This is the currently selected item.

Carbon can have an sp hybridization when it is bound to two other atoms with the help of two double bonds or one single and one triple bond. The easiest way to determine hybridization is to with the vsepr theory and determine the number of electron groups around your central atom. The hybrid orbitals used (and hence the hybridization) depends on how many electron groups are around the atom in question.
Chemists Use Hybridization To Explain Molecular Geometry.
The reason is that ethane, ethene and ethyne have sp3,sp2 and sp hybridization respectively. Calculate the steric number of central atom: Fluorine has 1 bond and 3 lone pairs giving a total of 4, making the hybridization:
