Question

I have #3 answered and the information given on the yellow sheet. How do know if Zaitsev's rule is obeyed?

also 4a and 4b?

ab parther Zotsev average GC retention time 2.147 average GC retention time 2.2 H-NMR assignment key HA Hc HD HE HH HB 13C-NMR assignment key 10 2 7 3 5 6 by GC G.12:1 El: Ratio 2-methyl-2-butene: 2-methyl-1-butene by 'H-NMR 1:01:1 by GC .4: 1 E2: Ratio 2-methyl-2-butene: 2-methyl-1-butene by H-NMR 1.31:1 3) Showing all work, use your experimental 'H-NMR data to calculate the ratio of the alkene products in each reaction. Express the ratios in the form xy where x - more abundanta and y 1. Compare these ratios to those obtained from your GC data and comment on the similarity of the values. State whether Zaitsev's rule is obeyed in both of the reactions. (8 pts 4) Use your answers to questions 1 - 4 and make detailed reference to the El and E2 reaction mechanisms to: te which elimination reaction is more selective for the Zaitsev product, making specific reference to your ratios of Zaitzev to non-Zaitzev products. (2 pts) a) sta b) explain why the two elimination reactions produce different ratios of Zaitzev to non-Zaitzev products despite the energy difference between the isomeric alkene products being independent of the mechanism by which they are formed.
