उत्तर
A hydrocarbon with the molecular formula C5H10 belongs to the group with a general molecular formula of CnH2n. Therefore, it may either be an alkene or a cycloalkane.
Since hydrocarbons do not react with chlorine in the dark, they cannot be alkenes. Thus, it should be a cycloalkane.
Further, the hydrocarbon gives a single monochloro compound, C5H9Cl, by reacting with chlorine in bright sunlight. Since a single monochloro compound is formed, the hydrocarbon must contain H-atoms that are all equivalent. Also, as all H-atoms of a cycloalkane are equivalent, the hydrocarbon must be a cycloalkane. Hence, the said compound is cyclopentane. The reactions involved are
