FOR OUESTIONS 25- 34. For all single replacement reactions below predict whether or not the reaction will occur using your activity series of metals. For all double replacement reactions predict the products and predict solubility for the reactants and products. Then, balance all reactions that occur. 25. Zn + Cuso, AB Yes, a reaction will occur. 26. KOH + H,SO, K_250_4+H_20. 2KOH + H_250_4-K_250_4-2H_20 27. Nal + B, AB No reaction 28. Bry + NaCl AB Yes, a reaction will...
2. For each of the chemical substitution reactions below identify the major products and whether the reaction is likely an SNI or SN2. Br NaCN ethanol-water CH,OH /H,0 Nal (1 equiv) acetone CH,CH,OH 25°C 3. For each of the following compounds provide appropriate reactants and solvent systems to synthesize them by a substitution reaction. Show which type of substitution: Syl or SN2. SH
11. For each of the following reactions, predict whether Syl or Sy2 will be the primary substitution mechanism. (Circle one) Br Nal in H2O - SN or SN2 CH,OH Sn1 or SN2 NaCN in DMSO Sn1 or S2 12. For the second reaction in question 11 (above), which do you think would react faster--the sec- ondary bromide or a secondary chloride (assuming the same reaction conditions)? (Circle one) Bromide Chloride Neither (rates are the same)
And which reaction occurs faster
Мар Consider the pair of reactions (1) and (2) below. (a) Predict the major organic and inorganic products of each reaction. (1) ^ NH2 DMSO 1 equiv. 1 equiv. (2) + DMSO B: 1 equiv. H2C-o: 1 equiv. (b) Determine whether the reactions will occur via the SN1, SN2, E1 or E2 mechanism. Select one below. O SNI continued below... OSN2 Ο Ε1 lo E2
3) Predict the major organic product for each of the reactions shown below. State which reaction path (e.g., SN2) was followed to arrive at the product you drew. NaSH Br Reaction Path: DBU CI Reaction Path: td KCI Br (solvent) Reaction Path: SA1 NaOH Reaction Path:

Predict whether the following reactions will occur or not. For those that do occur complete and balance the equation. Write "No Reaction" for those that do not occur. Include all subscripts ((s), (aq), etc.). 2. CoCaBr Al_Ni(NO), () What is the molarity of a silver() nitrate solution if 50.00 ml of the silverll) nitrate solution is reacted with magnesium, producing 3.580 g of dry silver metal? Include the balanced molecular equation in the space provided. 3. Balanced Molecular Equation:
3. Shown below are a series of reactions. Predict the major product for each of them. Remember, you will need to first decide whether the reaction occurs by an SN2, SN1, E2, or E1 before you can determine what the product will be. Label each as SN2, SN1, E2, or E1. Hint: First decide whether S2/E2 or S1/E1 is favored, and then decide whether the reaction pathway goes by a substitution or elimination reaction. SN2 / SN1 E2/E1 Na DMSO,rt...
4) For each of the following reactions, indicate whether the reaction would work well. poorly, or not at all. In such cases that you predict no production of the indicated product, formulate alternative products. Cl CN HCN H3C-OH NaOH acetone H3CnYCH3 Br OH 40°C CH3 Nal CH3 H3C HaC DMF CH3 CH3
Write out the products of the following reactions. Then, for each reaction, predict whether the products or reactants are more favored thermodynamically (i.e. if the equilibrium lies further towards reactants or products). Provide a brief explanation for each. a. LiCl + CuCN b. FeCl2 + MgI2 c. Pd(OAc)2 + 2 HI d. BF3•PMe3 + pyridine
