Each carbon has a single hydrogen atom attached to it. The lines in this figure represent the Ï bonds in benzene. The basic ring structure is composed of Ï bonds formed from overlap of sp2 hybrid orbitals on adjacent carbon atoms. The unhybridized carbon pz orbitals project above and below the plane of the ring.
When two sp orbitals are engaged in bonding, it is called a sigma bond. A triple bond is made of two pi bonds and one sigma bond. Examples of compounds with triple bonds include nitrogen gas, the cyanide ion, acetylene and carbon monoxide.To unlock this lesson you must be a Study.com Member.his is because nitrogen gas is made up of two nitrogen atoms held together by a triple bond. A triple bond is formed when two atoms are sharing three pairs of electrons. Triple bonds between atoms are often represented by three parallel lines. It is important to note that electrons are shared in pairs.
