If each of the five isomeric hexanes is monochlorinated and all possible structural isomers of $C X_{6} H X_{13} Cl$ are collected, what is the total number of distinct monochloro compounds (stereoisomers not counted)?

Answer: C

Distinct H environments: hexane 3, 2-methylpentane 5, 3-methylpentane 4, 2,2-dimethylbutane 3, 2,3-dimethylbutane 2. Different parent skeletons cannot give the same chloroalkane, so the total is 3 + 5 + 4 + 3 + 2 = 17.
