The carbons in alkenes and other atoms with a double bond are often sp2 hybridized and have trigonal planar geometry. Ethene (C 2 H 4) has a double bond between the carbons. In this case, carbon will sp 2 hybridize; in sp 2 hybridization, the 2s orbital mixes with only two of the three available 2p orbitals, forming a total of three sp hybrid orbitals with one p-orbital remaining. The three hybridized orbitals explain the three sigma bonds that each carbon forms. All the compounds of carbon containing a carbon-carbon double bond, Ethylene (C 2 H 4) sp 3 Hybridization When one ‘s’ orbital and 3 ‘p’ orbitals belonging to the same shell of an atom mix together to form four new equivalent orbital, the type of hybridization is called a tetrahedral hybridization or sp 3 . There are two ways to form sp 2 hybrid orbitals that result in two types of bonding.

There are three possible types of hybridization – sp 3, sp 2 and sp hybridization.

Valence Bond Theory: Hybridization Objectives To illustrate the distribution of electrons and rearrangement of orbitals in covalent bonding. Background Hybridization: In the formation of covalent bonds, electron orbitals overlap in order to form "molecular" orbitals, that is, those that contain the shared electrons that make up a covalent bond Hybridization of ethene. Carbon atoms have sp 2 hybridization. Hydrogen atoms are not hybridized because it has only s orbital.

Now consider ethene, C 2 H 4. Ethene forms a double bond between the carbons to satisfy the octet rule. The sp 3 hybrid orbital cannot explain this bond formation. In this case, sp hybridization leads to two double bonds. sp2 hybridization In ethene, carbon sp 2 hybridizes, because one π (pi) bond is required for the double bond between the carbons, and only three σ bonds form per carbon atom. Ethene structure Ethene has a double bond between the carbons.

Number of σ-bonds formed by the atom in a compound is equal to the number of other atoms with which it is directly linked to. In this case, sp-hybridization is seen to lead to two double bonds. Notice that the two C–O π bonds are mutually perpendicular. Similarly, in hydrogen cyanide, HCN, we assume that the carbon is sp-hybridized, since it is joined to only two other atoms, and is hence in a divalent state.

When one ‘s’ orbital and 3 ‘p’ orbitals belonging to the same shell of an atom mix together to form four new equivalent orbital, the type of hybridization is called a tetrahedral hybridization or sp 3. Double and triple bonds can be explained by orbital hybridization, or the ‘mixing’ of atomic orbitals to form new hybrid orbitals. Hybridization describes the bonding situation from a specific atom’s point of view. The unhybridized 2p orbital in both carbons are left available to form the double bond’s π bond.

A carbon atom is sp2 hybridized when bonding takes place between 1 s-orbital with two p orbitals. There is a formation of two single bonds and one double bond between three atoms. The hybrid orbitals are placed in a triangular arrangement with 120° angles between bonds. Example: Hybridization of graphite The double bond between carbon and oxygen consists of one σ and one π bond. The oxygen atom, like the carbon atom, also has a trigonal planar arrangement of the electrons that requires sp2hybridization. The σ bond in the double bond is formed from overlap of a carbon sp2hybrid orbital with an oxygen sp2 Triple bonds are not formed by sp3 hybrids.

Now when the hybridization happen, there is one less available p-orbtial, and so a total of 1 s orbital and 2 p-orbitals are mixed together to make three sp 2 orbitals. The three hybrids will be used to make Single covalent bonds that form between nuclei are created from the "head-to-head" overlap of orbitals and are called sigma (s) bonds. This overlap may involve s-s, s-p, s-d or even p-d orbitals. Another type of bond, a pi (p) bond is formed when two p orbitals overlap.
The three hybridized orbitals explain the three sigma bonds that each carbon forms. All the compounds of carbon containing a carbon-carbon double bond, Ethylene (C 2 H 4) sp 3 Hybridization When one ‘s’ orbital and 3 ‘p’ orbitals belonging to the same shell of an atom mix together to form four new equivalent orbital, the type of hybridization is called a tetrahedral hybridization or sp 3 . There are two ways to form sp 2 hybrid orbitals that result in two types of bonding. 1) hybridization of an element with three valence electrons in its outer shell, like boron will yield three full sp 2 hybrid orbitals and no left over electrons. now that we understand hybridization states let's do a couple of examples all right and so we're going to identify the hybridization States and predict the geometries for all the atoms in this molecule except for hydrogen and so let's start with this carbon right here so the fast way of identifying a hybridization state is to say ok that carbon has a double bond to it therefore it must be sp2 hybridized and if it's sp2 hybridized we know the geometry around that carbon must be trigonal In general, an atom with all single bonds is an sp3 hybridized.
