The heat of hydrogenation of cyclooctene is 97 kJ/mol. The heat of hydrogenation of cyclooctatetraene is 410 kJ/mol, more than four times the value for cyclooctene. The expected value for cyclooctatetraene (based on the value for cyclooctene) is 388 kJ/mol (4 x 97 kJ/mol).
The difference between the observed value and the expected value is the resonance stabilization energy, or -22 kJ/mol (388 kJ/mol - 410 kJ/mol). The negative sign indicating that full conjugation in cyclooctatetraene is destabilizing.
I am not certain how sign conventions are handled in this arena though.
What else can I help you with?
What is damping and how does affect resonance?
Damping is the dissipation of energy in a vibrating system. It affects resonance by reducing the amplitude of vibrations and slowing down the rate at which energy is exchanged between the system and its surroundings. Higher damping decreases the peak amplitude of resonance and widens the resonance frequency band.
Adding energy at the natural frequency of an object is called what?
Adding energy at the natural frequency of an object is called resonance. Resonance can lead to an increase in amplitude of vibrations, potentially causing the object to vibrate with greater intensity or even break.
When molecules collide and transfer energy it is called what?
When molecules collide and transfer energy, it is called a collision.
How can you quantify the resonus energy?
Resonance energy can be quantified by calculating the difference in energy between the actual energy of a molecule and the energy it would have if the bonds were perfectly localized or delocalized. This can be done using computational chemistry software to perform calculations on the molecule's electronic structure. The resonance energy provides a measure of the stabilization gained from delocalized bonding.
What is meant by resonance stabilized?
Resonance stabilization refers to the delocalization of electrons in a molecule through different possible resonance structures. This distribution helps to lower the overall energy of the molecule, making it more stable. Resonance stabilization is commonly seen in molecules with conjugated systems, such as in aromatic compounds like benzene.

What is ionic resonance energy?
Ionic resonance energy is the stabilization that results when two different ionic forms of the same compound or species are in equilibrium due to the transfer of electrons. It represents the energy required to convert one ionic form into another. This concept is important in understanding the behavior of ionic compounds in various chemical reactions.

When an object begins vibrating because it absorbs energy from another vibrating object?
Resonance
How does the concept of resonance influence the entropy of a system?
The concept of resonance can increase the entropy of a system by allowing for more ways for energy to be distributed among its components. This increased energy distribution leads to greater disorder and randomness, which are key aspects of entropy.
What occurs when vibrations through an object match the object's natural frequency?
When vibrations match an object's natural frequency, resonance occurs. This causes the object to absorb more energy and vibrate with a higher amplitude. In some cases, resonance can lead to structural failures or damage to the object.
