The difference between SN1 and SN2 reactions can be described by their stereochemistry: SN1 leads to racemization, while SN2 results in inversion of configuration. 8. Illustrate the difference between SN1 and SN2 mechanisms. The difference between SN1 and SN2 mechanism can be illustrated by SN1...

I am speaking of ring substituents, mainly. Is there a possiblity of having a large enough substiuent to cause the ring to change its shape(say a 1c4->4c1)to keep Nu- in the same stereochemistry as the leaving group? I am thinking maybe a nucleophile that would be so stable as axi...
2. What Really Happens In The Reaction of SOCl2With Secondary Alcohols: The SNi Mechanism In the late 19th century, Paul Walden performed a series of fundamental experiments on the stereochemistry of various reactions of sugars (and sugar derivatives). Walden noted that when (+)-malic acid treat...
Provide a mechanism for the following reaction. Use arrows (hint: this is a radical reaction so use single-headed arrows) to show the movement of electrons. Noting the curved arrows, draw all the product(s), organic and inorganic, of the following reaction. Do not consider stereo...
