Title: Help with a reaction...?
Post by: JMaria on July 28, 2014, 10:05:14 PM

So I have a reaction with 2-methyl-2-octene (lq) and HCl (lq) with heat and CH2Cl2.

I think the HCl adds in Markovnikov fashion but I've only seen the CH2Cl2 associated with halogenation and the heat with radical reactions so I'm not sure what it's there for.

As a solvent?

Well it has the 2-methyl-2-octene and then + HCl and then an arrow beside it with a delta on top and a CH2Cl2 on the bottom.

Then it is a solvent

So is the product 2-chloro-2-methyloctane? And the heat is required for the reaction to occur and the methylene chloride is the solvent which can be in excess?

Yes, that is the product.  Heat speeds the reaction up exponentially (k_forward), and it increases the yield (k_forward/k_backwards.  The solvent is in excess.
