As a students that majoring education program of chemistry, it is hard for me to undestand about what’s the different of E1 and SN1 reaction. Thank you your eexplanation about it.

In alcoholic medium secondary halides prefer SN1 mechanism?

In reply to adi. What's the rate determining step in the SN1? What factors influence this first step?

I had a question that as u have mentioned in text that heat favours elimination so is always valid even in case of Hoffman products

a tertiary carbocation or a resonance stabilized carbocation predominates in SN1 reactions…pls answer fast…

In reply to azmanam. HSO4- is the conjugate base. Since H2SO4 is a strong acid, HSO4- its conjugate base is a weak base.

Carbocation can give a proton to a base at elimination reaction. E1 is just alternative of SN1. Am I right?

Thank you.

In reply to azmanam. For H2SO4 I get a pKa of -3 or so, so I don't think it's unreasonable to draw it acting as a base. But I see your point, especially regarding the last part!

I disagree that the conjugate base of the strong acid is a competent base for the final deprotonation. It’s logical and makes the reaction obtain a certain amount of symmetry (especially if you stress that H2SO4 is catalytic), but imho HSO4- is too weak of a base to be a competent base in that deprotonation. Same with Cl- or TsO- or any of the other conjugate bases of strong acids. In my class, HSO4- as a base would be marked incorrect.

(… plus if it’s really catalytic, statistically water is present in a much larger quantity anyway)
