This was the fracking hardest thing of these 4 reactions was the stereochemistry of the SN1. In minutes you made sense of it for me. Drawing in the orbitals was inspired. Thank you!
I think that is just for chiral molecules but i'm no chemist. but I do know that racemic means 50/50 mixture and he said that it is not 50/50 so I don't think so
Exactly i also feel doubtful in that point, because in this video ruclips.net/video/sDZDgctzbkI/видео.htmlsi=9jEZwqKNgLsiwXGk ,it is said that 50% is produced
In the absence of a good nucleophile the carbocation is likely to undergo an E1 reaction to give an alkene or undergo solvolysis if the reaction is conducted in a polar protic solvent like methanol or water. In practice these other pathways may compete with the desired Sn1 reaction to a greater or lesser extent depending on the structure of the alkyl halide, the nucleophile and the reaction conditions (such a solvent and temperature) to produce unwanted by-products.
He said the carbocation is Sp2 hybridized and experiences a trigonal planar form when the halogen leaves the substrate, but what he drew isn't trigonal planar at 0:55...
I still agree with @europeankid98 tho, he drew wedged and dashed bonds which doesn't really signify trigonal planar. But maybe he did so just to visualize that the bonds of the starting molecule are still the same bonds within the carbocation intermediate?
I know this comment was 2 months ago but to answer your question, SN1 reaction occurs with partial racemization. Cause it isn't exactly 50/50, but a little higher/lower than that.

What are you doing these days?
Thank you! That was one of the clearest explanations of Sn1 reactions I've heard.

If you leave out the nucleophile will the leaving group go back to the carbon?

He was just drawing the plane that the three other molecules sit on. That square represents a flat surface

I was about to comment that
So isn’t this the same as saying the products are diastereomers? So, an SN1 reaction doesn’t always make a racemic mixture of enantiomers?

Hey this really helps thanks
thanks a lot. that was great explanation!
Can u say slowly and clearly right
Would this be a racemicmixture?
Wow
1.5 speed babyyyyyyy
