WebOct 20, 2024 · Ethane pi bonds. Ethane is made of sigma bonds. But understanding it first will help you understand the formation of pi bonds. According to valence orbital theory, the bonding structure of the ethane molecule is extremely similar to that of methane. Both carbons contain four bonds that are organised in a tetrahedral geometry because they … WebOct 12, 2024 · ethane: 350 kJ/mol -> 350 kJ/mol per bond; ethene: 610 kJ/mol -> 305 kJ/mol per bond; ethyne: 835 kJ/mol -> 278 kJ/mol per bond; In general: for any chosen approach, the sigma bond in ethane will be the strongest even though the bond distance of ethyne is the smallest. The additional electrons of the pi bond(s) destabilize the bond.
