Hybridization is based on the regions of electron density around the central atom. Because a triple bond and a single bond would mean that the carbon is bound to 2 atoms, it has sp hybridization because of the two regions. It would have 2 electrons in the sp orbital for 2 sigma bonds, and 2 unpaired electrons in the p-orbital for the two pi bonds.

When carbon atoms are bonded to other atoms, they use hybrid orbitals. A hybrid orbital is an electron orbital that forms when two atomic orbitals combine to 

Here, there are 2 C-H bonds and a triple C-C bond. Thus we expect the σ bonds from each carbon atom are formed using a set of sp 2 hybrid orbitals that result from hybridization of two of the 2p orbitals and the 2s orbital (Figure 8.22). These orbitals form the C–H single bonds and the σ bond in the C = C C = C double bond (Figure 8.23). Valence Bond Theory IV: sp2 Hybridization and Double Bonds. Watch later.

If you have one double bond, it is sp2. If you have two double bonds it is sp. So each double bond bring the degree of the p level down by 1. Also since a triple bond is formed by the overlap of two sets of unhybridized p orbitals, an atom that has one triple bond is spthe same hybridization as an atom with two double bonds. The unused p-orbitals can make two double bonds, a triple bond, or potentially participate in resonance with other orbitals. How Do We Determine Hybridization?

Hybridization is based on the regions of electron density around the central atom. Because a triple bond and a single bond would mean that the carbon is bound to 2 atoms, it has sp hybridization because of the two regions. It would have 2 electrons in the sp orbital for 2 sigma bonds, and 2 unpaired electrons in the p-orbital for the two pi bonds.

It would have 2 electrons in the sp orbital for 2 sigma bonds, and 2 unpaired electrons in the p-orbital for the two pi bonds. sp 2 Hybridization in Ethene and the Formation of a Double Bond 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. Thus, the sp 2 hybridization theory explains the double bond, the trigonal planar structure in ethylene molecule. Similarly, for a triple bond formation, like for that of acetylene molecule, there is sp hybridization between 1 s and 1 p orbital of the carbon atom.

The oxygen atom, like the carbon atom, also has a trigonal planar arrangement of the electrons that requires sp2 hybridization. The σ bond in the double bond is formed from overlap of a carbon sp2 hybrid orbital with an oxygen sp2 hybrid orbital. For this molecule, carbon sp 2 hybridises, because one π (pi) bond is required for the double bond between the carbons and only three σ bonds are formed per carbon atom.

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. Multiple bonds can also occur between dissimilar atoms. When the two O-atoms are brought up to opposite sides of the carbon atom in carbon dioxide, one of the p orbitals on each oxygen forms a pi bond with one of the carbon p-orbitals. In this case, sp hybridization leads to two double bonds. Sigma and pi bonds the hybridization model helps explain molecules with double or triple bonds (see figure 1 below).

It has 14 valence electrons, and all of them participate in forming bonds. In the Lewis structure of CH 3 Cl, Carbon is at the central position and all the other atoms around it. The bond angles of Carbon with Hydrogen and Chlorine atoms are 109.5 degrees. This molecule has a tetrahedral shape, and the central carbon atom has sp3 hybridization.

Triple bonds are not formed by sp3 hybrids. Carbon, in a molecule like ethyne, is in the sp hybridization state, that is, it mixes its 2s atomic orbital (AO) and one of its 2p orbitals to form 2 sp hybrid orbitals (HO’s).

Double bonds - 1 sigma and 1 pi bond; Triple bonds - 1 sigma and 2 pi bonds. 14.2.2: Explain Hybridization in terms of the mixing of atomic orbitals to form new  

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.
