Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". This further leads to the formation of 4 sp hybridized orbitals wherein each CH molecule will form 2 hybridized sp orbitals. sp hybridization : This type of hybridization involves the mixing of one s and one p orbital resulting in the formation of two equivalent sp hybrid orbitals. N2H2 may exist (probably only transiently, though) - it might be one of the intermediates in the reduction of nitrogen to ammonia by dinitrogenase enzymes (generally iron- or molybdenum- containing, these metal ions being electron donors in the reductive process) in species such as Azotobacter. It made four identical bonds in a perfect tetrahedral geometry, which means it needed four identical orbitals to make those bonds..
