A compound $A$ contains $C$ and $H$ only and has molecular mass 72. It's photochlorination gives a mixture containing only one monochloro and two dichloro hydrocarbons. The IUPAC name is
2, 2-dimethylpropane
n-pentane
2-methyl butane
cyclopentane
Solution
$\mathrm{C}_5 \mathrm{H}_{12}$, pentane has molecular mass $72 \mathrm{~g}$ i.e. the isomer of pentane which yields single monochloro derivative and two dichloro derivative is 2, 2-dimethyl propane as it has all equivalent hydrogens.
