The discussion clarifies the bond energy comparison between sigma and pi bonds, specifically addressing the C=O and C-O bonds. The bond energy values are 745 KJ for C=O and 358 KJ for C-O, leading to a calculated pi bond energy of 387 KJ. This calculation raises questions about the strength of pi bonds compared to sigma bonds. The confusion arises from comparing the sp3 hybridized C-O bond with the sp2 hybridized C=O bond, highlighting the importance of hybridization in bond strength analysis.
PREREQUISITESChemistry students, educators, and professionals interested in molecular bonding, particularly those focusing on bond strength and hybridization effects.
In this case, your table lists the sp3 hybridized sigma carbon-oxygen strength ( C-O) rather than the sp2 hybridized sigma carbon-oxygen strength (C=O). Comparing apples and oranges...r12214001 said:Summary: bond energy
It is well known that sigma bond is stronger than Pi bond. However in bond energy table that C=O is 745 KJ and C-O is 358 KJ. we can calculate the Pi bond energy is 745-358=387! The Pi bond(387KJ) is stronger than sigma bond(358KJ) ? How could this happen?
