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?
A Pi bond is a type of covalent bond formed by the sideways overlap of atomic orbitals, while a sigma bond is formed by the head-on overlap of atomic orbitals. Pi bonds are weaker than sigma bonds due to the smaller overlap of orbitals.
The bond energy of a Pi bond and a sigma bond is determined by the strength of the bond between the two atoms. This strength is influenced by factors such as the types of atoms involved, the distance between them, and the number of bonds present.
Yes, the bond energy of a Pi bond and a sigma bond can be affected by external factors such as temperature, pressure, and the presence of other molecules. These factors can alter the strength of the bond and thus affect the bond energy.
The bond energy of a Pi bond and a sigma bond contributes to the overall stability of a molecule. The stronger the bond, the more stable the molecule will be. This is because stronger bonds require more energy to break, making it less likely for the molecule to undergo chemical reactions.
Pi bonds are generally more reactive than sigma bonds. This is because the sideways overlap of Pi bonds allows for easier rotation and breaking of the bond, making it more susceptible to chemical reactions. Sigma bonds, on the other hand, have a stronger head-on overlap and are less likely to undergo reactions.
