The question is about identifying the type of energy difference seen in resonance structures of a compound. To answer this, let's break down the key terms:
From the provided options, the correct term describing the energy difference between the actual structure and the lowest energy resonance structure is Resonance Energy. This term accurately represents the stabilization energy that makes the actual structure more stable than any single resonance form.
Thus, the correct answer is:
Resonance Energy
- The difference in energy between the actual structure of a molecule and its most stable resonance structure is known as resonance energy. - Resonance energy indicates the extra stability gained by a compound due to resonance, where electrons are delocalized across atoms.
So, the correct answer is: Resonance Energy (2)
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)

Cobalt chloride when dissolved in water forms pink colored complex $X$ which has octahedral geometry. This solution on treating with cone $HCl$ forms deep blue complex, $\underline{Y}$ which has a $\underline{Z}$ geometry $X, Y$ and $Z$, respectively, are
Relative stability of the contributing structures is :
