The given reaction involves a molecule of C5H10 undergoing a photochemical reaction (indicated by \(h\nu\), where \(\nu\) represents light). When light is used to excite this molecule, it can lead to the formation of structural isomers by breaking bonds or rearranging atoms.
To determine the number of possible structural isomers, we can look at the different ways the carbon atoms can be arranged while maintaining the molecular formula C5H10.
- In the simplest case, we have a straight chain of 5 carbon atoms, which gives us pentane (C5H12) with the hydrogen atoms filling the remaining bonds. - Then, branching of the carbon chain can give rise to different structural isomers like 2-methylbutane and 3-methylbutane, where one or two of the carbons branch off the main chain.
Thus, there are 3 structural isomers of C5H10 that can result from this photochemical reaction.
Therefore, the correct number of possible structural isomers is 3.
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
