And what do you think of the answers you have been given here? Do you now understand?

So the one with the Fluoro isn't stable?

But with E1 it will be a carbocation, surely, which Me can stabilise as alkyl groups are slightly electron-donating? (I admit it's many years since I did this stuff.) 

It's an E2. I wanted to know which alkene is more stable. Only this

Ah, is this about the Zaitsev Rule?  

I don't think so, we didn't study this rule.

 it's an elimination reaction (E2) with NH3 as a solvent. The substrate is: 2-methyl-3-Chloro-4-Fluoropentane.

The products are two alkenes (i put them in the photo but I don't why you can't see it). One of the alkenes has the the double bond on the C2-C3. The other one on the C3-C4. 

My professor wanted to know which product is more stable.

What does "do an E2 with NH3 on the 2-metyl-3R-Cl-4S-F pentane"mean? E2 I assume means an elimination reaction, somehow involving ammonia, but what are the substituents on pentane and what were the 2 products? There seems to be a .jpg file attached which we can't see. 

If you use a few more words, it may help to clarify what this is about.  

Yes it's an elimination reaction (E2) with NH3 as a solvent. The substrate is: 2-methyl-3-Chloro-4-Fluoropentane.

The products are two alkenes (i put them in the photo but I don't why you can't see it). One of the alkenes has the the double bond on the C2-C3. The other one on the C3-C4.

The attachment  is broken. Can not open.

What attachment?

Hi, a few days ago i took an exam and there was an exercise that required to do a scale of stability of the alkenes. 

I had to do an E2 with NH3 on the 2-metyl-3R-Cl-4S-F pentane. I obtaneid these two. Which is more stable and why?

Sorry i forgot the F on the second one.
