There are 4 (C-H) bonds (sigma) and 1 (C-C) bond (sigma). Sigma bonds are a result of the head-to-head overlapping of atomic orbitals whereas pi bonds are formed by the lateral overlap of two atomic orbitals.Various bond parameters such as bond length, bond angle, and bond enthalpy depend on the way the overlapping of atomic orbital takes place. bond. The carbon atom consists of 6 electrons and hydrogen has 1electron. The pi bond dominates the chemistry of ethene. heart outlined. sigma and pi-bonds are just ways in which electron orbitals interact to form bonds - sigma are stronger bonds, but you can't have more than one between the same two atoms. A pi-bond is always present in it. Sigma vs pi Bonds . Sigma and pi bonds are chemical covalent bonds. In total, 5 sigma & 1 pi. These two perpendicular pairs of p orbitals form two pi bonds between the carbons, resulting in a triple bond overall (one sigma bond plus two pi bonds).
