Chapter 9: Substitution and Elimination be the reactions as either SN1 or SN2, then draw the...
which substitution and elimination reactions follows Zaitsev’s rule? SN1, E1, SN2, E2?
Draw the major, neutral organic product obtained if: the reaction proceeds by the SN1 mechanism the reaction proceeds by the SN2 mechanism. Draw the major, neutral organic product for each substitution reaction below. (For this question, assume that each substitution reaction goes to completion. Disregard elimination.) Draw the major, neutral organic product obtained if: the reaction proceeds by the SN1 mechanism the reaction proceeds by the SN2 mechanism. Draw the major, neutral organic product for each substitution reaction below. (For...
D. Substitution Reactions: Use your own nucleophile and Draw the product/s. a. Sn1 b. SN2
4. Sn1 reactions are unimolecular and Sn2 reactions are bimolecular. What does this mean? Write the generic rate laws for Sn1 and Sn2 reactions. Which reagents do the rates of Sn1 and Sn2 reactions depend on? 5. Consider tert-butylchloride and 2-chloropropane. Which of these compounds is more likely to react via an Sn1 mechanism? Which is more likely to reactive via an Sn2 mechanism? Explain your answer. 6. Rank the following compounds in order of increasing likelihood of undergoing substitution...

What substitution mechanism (Sn1, SN2, both, or neither) is expected for the following compound? Br What substitution mechanism (Sn1, SN2, both, or neither) is expected for the following reaction? -nucleophile attacks 12 - inversion of conf SCH
can someone please explain to me how to tell whether substitution (sn1/sn2) or Elimination (E1/E2) im mostly confused on nucleophile or base strong or weak like is there a step by step that you know thats great for knowing what mechanisms to use ? please please be descriptive . write steps to finish mechanism. and explain nucleophile/base/strong/weak and what goes with what mech.
