The amount of energy required to break a bond is same as the amount of energy released when the same bond is formed. In gaseous state, the energy required for homolytic cleavage of a bond is called Bond Dissociation Energy (BDE) or Bond Strength. BDE is affected by s-character of the bond and the stability of the radicals formed. Shorter bonds are typically stronger bonds. BDEs for some bonds are given below:
Correct match of the C-H bonds (shown in bold) in Column J with their BDE in Column K is
F or the following reaction
the correct statement is
Paragraph
The reaction of $$K_3[Fe(CN)_6]$$ with freshly prepared $$FeSO_4$$ solution produces a dark blue precipitate called Turnbull’s blue. Reaction of $$K_4[Fe(CN)_6]$$ with the $$FeSO_4$$ solution in complete absence of air produces a white precipitate X, which turns blue in air. Mixing the $$FeSO_4$$ solution with $$NaNO_3$$, followed by a slow addition of concentrated $$H_2SO_4$$ through the side of the test tube produces a brown ring.
Among the following, the brown ring is due to the formation of
For the following questions answer them individually
One mole of an ideal gas at 900 K, undergoes two reversible processes, I followed by II, as shown below. If the work done by the gas in the two processes are same, the value of $$\ln \frac{V_3}{V_2}$$ is ___.
(U: internal energy, S: entropy, p: pressure, V: volume, R: gas constant)
(Given: molar heat capacity at constant volume, $$𝐶_{𝑉,𝑚}$$ of the gas is $$\frac{5}{2}R$$)
Consider a helium (He) atom that absorbs a photon of wavelength 330 nm. The change in the velocity (in cm s$$^{-1}$$) of He atom after the photon absorption is ___.
(Assume: Momentum is conserved when photon is absorbed.
Use: Planck constant = $$6.6 \times 10^{-34}$$ J s, Avogadro number = $$6 \times 10^{23} mol^{-1}$$, Molar mass of He = 4 g mol$$^{-1}$$)
Ozonolysis of $$ClO_2$$ produces an oxide of chlorine. The average oxidation state of chlorine in this oxide is ___.
