How many different monochlorobutanes (including stereoisomers) are formed in the free radical chlorination of butane?

Question image

Understand the Problem

The question is asking for the number of different monochlorobutanes produced during the free radical chlorination of butane, considering all stereoisomers. This involves understanding the mechanisms of free radical reactions and the resulting structural isomers.

Answer

3

The final answer is 3.

Answer for screen readers

The final answer is 3.

More Information

In butane, chlorination can occur at the primary or secondary carbons. Chlorination at the 2nd carbon creates a chiral center, resulting in two enantiomers (stereoisomers), while chlorination at the 1st carbon gives one structural isomer.

Tips

A common mistake is to overlook the creation of stereoisomers from chiral centers, which doubles the number of isomers for those cases.
