Es SN1 porque el carbono unido al bromo es terciario, lo que favorece la formación de un carbocatión estable, necesario para el mecanismo SN1.

English, please. What’s considered the international language of science.

This appears to be either an answer to a question or an explanation in a text.

What do you want to know about it and yes English please. ?

SN1 and SN2 are types of chemical substitution reactions

Buen dia. Guessing a bit, as I don't speak Spanish but have some French and Latin, the SN1 mechanism is favoured with tertiary carbon atoms because the substituents hinder access by a displacing anion, as it needs to approach from the side opposite to the group to be displaced. So SN2 doesn't work. Details here (using the example of hydroxide as the displacing species and bromine as the species to be displaced) :

It is also true that tertiary carbocations are somewhat more stable than primary ones:

This is actually quite interesting. I was brought up with the "traditional" explanation that alkyl groups were mildly electron-donating, without any compelling explanation as to why this should be. The more modern hyperconjugation explanation described in this link is new to me, but makes sense of it quite elegantly.

I hope you can read these explanation in English or, if not, that you can follow the diagrams. 🙂

and me Thanks +1

Don't you wish we could all learn something new everyday ?

Yep, that's why I always read these posts by newcomers. You never know what bit of extra knowledge you may glean. Even from cranks like Tom Booth!

But this looks like a serious enquiry. I had always found SN1 vs. SN2 one of the most boring and hackneyed topics in organic chemistry. Now, 50 years on, I find a new source of interest in it.
