1) Why is the CH3 going away in green arrow is just drawn as a normal bond with no stereochemistry in the products? 2) Why did we get two products 3) whats the major product?
1) Same thing why did the CH3 bond coming in get drawn as a normal bond here?
1) Whats the major product here 2) Why get a triple bond, how did they do that? 3) Do I need to draw both or is the first alkene product okay?
1) In I. Why did the Br bond not go away and instead we get a CH3 group from i don't know where and the H goes up top? 2) In m. Also same thing, why Br bond is replaced with CH3 and why H is alternating in this E1?
All in all: I was under impression that only SN1/SN2 go through inversion/racemic products but the stereochemistry in the above E1/E2 is kind of weird and I am a lil bit confused on that.
