The total number of monohalogenated organic products in the following (including stereoisomers) reaction is ____.
Answer: 8
Solution
Free-radical halogenation replaces a hydrogen at each distinct type of position in the molecule, and wherever the substitution creates a stereocentre the product appears as more than one stereoisomer. Counting every distinct monohalogenated product, including the enantiomers and diastereomers so generated, gives a total of 8.
