- 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)
In a resonance tube closed at one end. Resonance is obtained at lengths \( l_1 = 120 \, \text{cm} \) and \( l_2 = 200 \, \text{cm} \). If \( v_s = 340 \, \text{m/s} \), find the frequency of sound.
Let $ P_n = \alpha^n + \beta^n $, $ n \in \mathbb{N} $. If $ P_{10} = 123,\ P_9 = 76,\ P_8 = 47 $ and $ P_1 = 1 $, then the quadratic equation having roots $ \alpha $ and $ \frac{1}{\beta} $ is:
