Question
Which isomer of C5H10 gives a single monochloro compound C5H9Cl in bright sunlight?
Solution
The molecular formula C5H10 can have a number of structural isomers.
However, the fact that the given compound produces a single monochloro derivative when reacted with Cl2 in sunlight implies that all of the H-atoms in the compound are equivalent. This is possible only if the compound is a cyclic alkane. Hence, the hydrocarbon is cyclopentane.
