Alkenes
« on: January 31, 2007, 12:05:27 PM »
When 2-butene reacts with hydrogen chloride gas, only one product is detected,
whereas when 1-butene reacts similarly, two products are usually found. Explain this.   

I need help with this guys!

They are both alkenes, so have double C=C bonds but I am not sure what to do or how to figure it out?!

You mean 2-butene gives two products in moderate yields.

1-Butene cannot give two products.  It can only give one.  The other one is practically hypothetical.  Maybe you read the question wrong?

I don't think so. I can only see one product forming from HCl + 2-butene.
1-butene could give two, although one major.

Kayleyrvt, what is the product from the HCl + 2-butene reaction?

You know the reaction with 1-butene is similar, so what are the possible products?

Aye.  I didn't see the symmetry.

is the reaction for 2-butene 2-chlorobutene???
I am saing this because you are really adding chlorine to it.

I don't understand this really.
I know that to break the double bonds, you have to add a H and a Cl to the C atoms that have the double bonds. That's about all I can figure out :(
