In both examples below the reactants shown are combined to bring about a nucleophilic substitution (Sy1, Sx2) and/or elimination (El, E2) reaction. What is the major reaction that takes place in each case? astered CH,CI NaOH H20 CH, N2OCH,CH, CH;CH,OH CH3 Br F. In both examples below the reactants shown are combined to bring about a nucleophilic substitution (S,x1, S,2) and/or elimination (E1, E2) reaction. What is the major reaction that takes place in each case? CH, CH, CH,CH,CHCCH, H,0 CH, KOC(CH3) CH,CHCH,CH,CH,Br (CH),COH ALL ARE APART OF ONE QUESTION!! PLEASE HELP!!! E.

7. The reaction of methoxide anion with bromoethane to yield the ether ethyl methyl ether and the bromide anon (Br-) is an excellent example of a general reaction type called Sy2 (substitution nucleophilic bimolecular): CH,0+ CH,СH-Br a CH3-0-CH,СH; + Br- a. Change in enthalpy is -103 kJ/mol; the change in entropy is + 0.025 kJ/mol-K. Calculate DG at 300K. b. Is the reaction endergonic or exergonic? c. Is the reaction endothermic or exothermic? d. Use curved arrows to show the complete mechanism. Reaction of 2-methyl-1-butene with H-Cl could yield TWO alkyl chloride products. Draw and name 8. them.

B. Supply the missing product or reagent for the following reactions OH ОН OH PCC POCI3,, pyridine HBr, heat OH OH Br Mg H₂SO4, heat 1) NaH 2) Ph Br

Predict the product
