A hydrocarbon of molecular mass 72 g mol–1 gives a single monochloro derivative and two dichloro derivatives on photo chlorination. Give the structure of the hydrocarbon.


The hydrocarbon that has molecular mass of 72g mol-1 is the alkane C5H12. The tert-isomer of pentane that on photo-chlorination gives a single monochloro derivative and two dichloro derivatives. The structure of the alkane and the chloride derivatives are given as follows.
