How does bonding and antibonding molecular orbitals interaction stabilize Molecules?
elena-s [515]

Answer:

Both decrease the energy of the atomic orbitals to form the molecule by their overlap

Explanation:

Many molecules are not described correctly by Lewis theory. For example, diborane (B2H6), which is an electrodeficient compound: there are not enough valence electrons to be able to assign a Lewis structure.

The theory of binding and anti-binding orbitals describes molecular orbitals, whose atomic orbitals overlap to form them. Two atomic orbitals overlap giving a binding orbital molecular orbital. In the binder, the electrons that occupy it have a high possibility of being located between the atoms, so filling stabilizes the molecule. In an anti-binding orbital, the electrons that occupy it have a low probability of being located between the atoms, so that their filling destabilizes the molecule.

The interaction between two atomic orbitals is greater the greater their overlap and the smaller their energy difference.

Zina [86]
When the solute can no longer dissolve in the solution the solvent becomes SATURATED. When no more solute can dissolve and if you look at the bottom of the beaker, test tube, pan, or glass of cold tea you can see the solute permeating out as little particles .

The ΔH vap of a certain compound is 46.55 kJ⋅ mol−1 and its ΔS vap is 67.37 J⋅mol−1⋅K−1.
arsen [322]

690 Kelvin is the boiling point of this compound.

Explanation:

Enthalpy is the sum of internal energy and the product of pressure and volume that is how much energy is in the substance.

Entropy is the measurement of randomness and measure of thermal energy per unit of temperature.

ΔH vap of compound is 46.55 kJ⋅ mol− or  J.MOL-1

ΔS vap  is 67.37 J⋅mol−1⋅K−1.

The boiling point or temperature can be calculated by the formula:

T= \frac{ΔH vap}{ΔS vap}

T =\frac{46550}{67.37}      

  = 690 Kelvin

The boiling point is the temperature when atmospheric temperature gets equal to
