A hydrocarbon C5H10 does not react with chlorine but gives a single monochloro compound, C5H9Cl in bright sunlight. Identify the hydrocarbon.
(i) The hydrocarbon with M.F. C5H10 can be either a cycloalkane or an alkene.
(ii) Since the hydrocarbon does not react with Cl2 in the presence of bright sunlight, to give a single monochloro compound, C5H9Cl, therefore, all the ten hydrogen atoms of the cycloalkane must be equivalent. Thus, the cycloalkane is cyclopentane.
