Graphene hybrid orbital
WebFinally, the hybrid orbital concept applies well to triple-bonded groups, such as alkynes and nitriles. Consider, for example, the structure of ethyne (common name acetylene), the simplest alkyne. This molecule is linear: all four atoms lie in a straight line. The carbon-carbon triple bond is only 1.20Å long. WebThe electron in the 2pz orbital remains in the 2pz orbital. The hybrid orbitals are formed from the electrons in 1s orbital and 2p orbitals. Thus, it is known as sp2 hybridization. …
