The given statements are true or false is to be explained. Concept introduction: Bond enthalpy is the energy released when one mole of a bond is broken. Octet rule states that every element present in the maingroups should have eight electrons in its valence shell in order to attain a noble gas configuration. Change of enthalpy of reaction is given by the difference of bond enthalpies of the products and bond enthalpies of the reactants. For variousmolecules, it is impossible to explain all their properties by a single Lewis structure. In such cases, more than one Lewis structures are drawn. Such a structure of a compound is called a resonating structure and this phenomenon is called resonance. Resonance structures areimaginary structures and not real ones.

The given statements are true or false is to be explained.
Concept introduction:
Bond enthalpy is the energy released when one mole of a bond is broken.
Octet rule states that every element present in the maingroups should have eight electrons in its valence shell in order to attain a noble gas configuration.
Change of enthalpy of reaction is given by the difference of bond enthalpies of the products and bond enthalpies of the reactants.
For variousmolecules, it is impossible to explain all their properties by a single Lewis structure. In such cases, more than one Lewis structures are drawn. Such a structure of a compound is called a resonating structure and this phenomenon is called resonance.
Resonance structures areimaginary structures and not real ones.
Aluminum oxide (Al₂ O₃) is a widely used industrial abrasive(emery, corundum), for which the specific application depends onthe hardness of the crystal. What does this hardness imply about the magnitude of the lattice energy? Would you have predictedfrom the chemical formula that Al₂ O₃ is hard? Explain.
Write the Lewis structures for CH2N2, including all resonance forms, and show formal charges.
