Isopentane chlorine substitution reaction
« on: February 16, 2020, 02:13:49 PM »
Hello everyone,,
I have a question. Lets say we have isopentane and Cl2 in a substitution reaction. How many different Carbon atoms can chlorine atom bond with? All five or can it substitute with a hydrogen that bonded to methyl brach?

It is an easy question maybe but please answer that is really important for me.

Thanks for your consideration..

It can bond with all of them and also several times until all hydrogen is exchanged. It will start with the second C.

For reasons you can look up elsewhere, free radical chlorination is usually "non-selective".  That means there are significant amounts of all possible products.

Isopentane gives 4 different monochlorination products - do you know why there are not 5?

There are many many more dichlorinationand, trichlorination products and so on. 

If you use a sufficient excess of chlorine you can end up with the perchloro product - all H's replaced with Cl.
