1 A good example of sp 3 hybridization is the methane CH 4 molecule. The methane molecule has a tetrahedral shape. Thus the sp 2 hybridization leads to carbon double bonds. For sp hybridization the molecule of ethyne is an example. When a carbon atom forms a compound, it always forms covalent bonds.
Sigma bonds are strong and the electron sharing is maximum.
Methane CH 4 is a good example for sigma bond and it has four of them. In pi bonds the resulting overlap is not maximum and these bonds are relatively weak. In pi bonds the resulting overlap is not maximum and these bonds are relatively weak. Thus carbon compounds formed due to double and triple bonds are called unsaturated carbon compounds.
