Secondary alkyl halide, if we use aprotic solvent like DMF, DMSO, I, CN it favors SN2 mechanism. If we use protic solvent Including water, methanol, it will favour SN1 and E1 mechanism. Sterically hindered Secondary alkyl halide with strong base and bulky group give E2 mechanism over SN2.

Fair point- I think that was just a slip-up on his part As far as I can tell, he's basically trying to say that the base always takes precedence over the solvent. That said, yes.

The substrate is on secondary carbon and has a stronger base in the reaction, so even though the protic solvet is used, the SN2/E2 would occur. If it is a protic solvent but no strong base, then SN1/E1 would then occur. If you look at his table at the beginning of the video he lists the reactions depending on the solvents/bases used.

@amanmohamed4783 жыл бұрын
Sterically hindered basically means the reaction can't happen coz group is too bulky, in a way it literally body blocks the incoming nucleophile if the compound has multiple branches that's why tertiary C is bad for Sn2
@sthvxa3 жыл бұрын
It's like heavy groups surrounding an atom. As you can think of a carbon atom surrounded by 3 methyl groups which doesn't allow other molecules to attack on it. It basically gives repulsions to the attacking molecule.

@paolaortiz63 жыл бұрын
-OCH3 is a strong base, so you would not be able to form C+
@georgieacero70433 жыл бұрын
Kinda late but for whoever else was wondering, looking at problems like these I believe that even in the presence of protic solvent, as long as you have a strong base it will go E2/SN2. The solvent is a rule to follow, but more of a hint that MAYBE the mechanism will want to go E1/SN1, you have to look at the whole mechanism as a hole and figure out what will really happen. Usually most mechanisms can be dictated by looking at possible carbocations and the strengh/bulkiness of the base/nucleophile Edit: Think of it like this, the NaOCH3 used will ionize into Na+ and OCH3-, it will continuously create another OCH3 by taking the H from CH3OH, therefore regardless of having a protic solvent, you’ll always also have strong base/nucleophile present. Now, here’s a tricky part, at the end then which will you get most of SN2 or E2? For this you have to look at the SIZE of the base/nucleophile. Anything smaller than ETHANOL will act as a base = Elimination product Anything larger than ETHANOL will act as a nucleophile = substitution product WITH THE EXCEPTION OF: Acetate ion, Sulfurs, and negative carbons!

You know that normally OH- is basic as it was the case for an acid like NaOH kOH, BaOH CaOH, just with OH- itself they are strong bases. Now if we replace H with an R group( electron donating), it will cause increase in charge over the oxygen which makes it more electron dense than OH- and hence a stronger base (think of it as a lewis base) than OH-, and OH- itself is a strong base (pOH~ 12-13)
