C5H10 \(\xrightarrow{h\nu}\) possible structural isomers?
Show Hint
Correct Answer: 3
Solution and Explanation
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.

- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure).
