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...
Q. Predict mechanism type (SN1, E1, SN2, E2) for the following reactions. If more than one is possible, predict which mechanism is more likely and explain why. 5 - HI ح . 0H SNI KOCH2CH3 KOCHCH - I want to wors. NaOH, H2O, 100°C في NaCN ي . HO )..NC دا SN2
please explain why and how they are E2/SN2/SN1/E1
3. Draw a structural formula for the major organic product(s) of each reaction and specify the mechanism by which each product is formed (SNI, S2, El, or E2). • NaOH H20 CH,CH ON CH,CH OH CH ON CH,OH CH OH Na DMSO
Write the major products and state whether it is SN1, SN2, E1, E2,
E1cB, or none of the above. Show all stereochemistry.
Write the major product(s), and state whether it is Syl, Sy2, El, E2, ElcB, or none of the above. III. Clearly show all stereochemistry ОТ NH2 + CH, сH,он CH, н сH, sOcyBenzene н н. он H H H H сн,сн, NBS/CC оть CH Н.С H H PBr HO H Н- нн н.с H Cl CH CH3 (CH)o8...
1) Compare and contrast SN1, SN2, E1, and E2 reactions!
(similarities abd differences. Requirements for each to
work.)
2) Why is SN2 is in direct competition with E2 while SN1 is
direct competition with E1 reaction.
3) Rate expression of each
4) which reactions are concerted? Which are atep wise?
5) which are sterospecific and what stereospecificity of each
are?
6) how do the variables below (A-D) influence reaction
pathway?
Compare and contrast SNI, SN2, El and E2 reactions. What...
