This question is about 2-Chloropropane. 2-Chloropropane can be produced by reacting propane with chlorine in a homolytic free radical reaction. (i) Show the initiation step of this reaction. Include appropriate arrows and the conditions necessary for this step. (2) (ii) Using your answer to (b)(i), state what is meant by the terms homolytic and free radical. (2) homolytic ................................................................................................................................................................................................................................................................................ ................................................................................................................................................................................................................................................................................ free radical ................................................................................................................................................................................................................................................................................ ................................................................................................................................................................................................................................................................................ (iii) Suggest why this method has limited use in the synthesis of organic compounds. (1)

Answer:

An answer that makes reference to the following points:
- homolytic: each atom gets one electron/ the electron pair splits evenly
- free radical: species with an unpaired electron
An answer that makes reference to the following point:
- multiple substitutions can occur/ more than one (organic) product
