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.

Compare and contrast SN1, SN2, E1 and E2 reactions. What are some obvious similarities and differences between each reaction pathway? What are the requirements for each reaction to work? Discuss why SN2 is in direct competition with E2 while SN1 is in direct competition with the E1 reaction pathway. What is the rate expression for each? Which reactions are concerted? Which reactions are step-wise? Which reactions are stereospecific and what is the stereospecificity of each that are? How do the...
