The first bond in a triple bond is due to end-to-end overlapping of atomic orbitals. A triple bond involves the sharing of six electrons, with a sigma bond and two [latex]\pi[/latex] bonds. In acetylene the ##CC## triple bond consists of a sigma bond and two pi bonds. The entire molecule is planar. They then can have extra pi bonds around the central sigma bond, forming double or triple bonds. The hybridization model helps explain molecules with double or triple bonds (see Figure 1 below). Ethene (C 2 H 4) contains a double covalent bond between the two carbon atoms and single bonds between the carbon atoms and the hydrogen atoms. A double bond will have a sigma and a pi bond: 1sigma + 1pi A triple bond would have 1sigma + 2pi A quadruple bond would have 1sigma + 3pi, and so on. And CBN, the first bond being a sigma bond, and the second / third bond being pi bonds. Likewise, a triple bond consists of one sigma bond and two pi bonds. The figure below illustrates the sigma and pi bonds in an ethylene molecule (C 2 H 4 C_2H_4 C 2 H 4 ). The basic C - H bond or C-X bond would be an illustration of Sigma bonds, while definitions of pi bonds would be C= O. This way of bonding is known as covalent bonding and this is shown mainly by non-metals and H +. 1sigma + 2pi There are 2 pi bonds. Generally, double bonds consist of one sigma and one pi bond, whereas a typical triple bond is made up of two π bonds and one σ bond. Sigma bonds are the FIRST bonds to be made between two atoms. There are 6 electrons in a triple bond; 2 sigma electrons and 4 pi electrons. Pi bonds are the SECOND and THIRD bonds to be made. Put it simply, single bonds are sigma bonds, and double / triple bonds are Pi bonds. Overall this sigma-pi picture of the double bond is reminiscent of a hot dog in a bun. A Triple bond has 1 sigma bond & 2 pi bonds. The second and third bonds are due to double overlapping of atomic p orbitals. Pi bonds contain two electrons each. These are the two pi bonds in a triple bond. They are made from hybridized orbitals. Overlap of p orbitals involved in a pi bond prevents rotation about double and triple bonds. Here’s a video on counting sigma and pi bonds. When a sigma and pi bond exist between two atoms, a double bond is formed. A chemical (covalent) bond is always made of one sigma bond. The pi bonds are formed by the side-on overlap of ##2p## orbitals. This is the sigma bond. Pi bond can't exist independently of a sigma bond. The sigma bond is formed by the head-on overlap of two ##sp## orbitals. When a sigma and 2 pi bonds exist, a triple bond is formed. Because the pi bond has less electron density between the atoms, it is of higher energy in the MO diagram and is weaker than the sigma bond. It’s just that simple. The sigma bond (σ bond) corresponds to the frankfurter, while the pi bond corresponds to the bun on either side of it. A triple bond contains one sigma bond and 2 pi bonds. Sigma and Pi Bonds. Pi Bonds are generally weaker than sigma bonds, owing to the significantly lower degree of overlapping. In single bond, 2 electrons are shared, in double bond four electrons are shared and in triple bond six electrons are shared. Note that every single bond consists of one sigma bond, and that the double bond is made of one sigma bond and one pi bond.
