After running the following reaction (shown below) you analyze your crude product and observe that it is a mixture of the product, diphenyl methanol, and the starting material, benzophenone. To purify your product, you choose to run a column. Describe in detail how to separate these two compounds using a silica gel column that has already been packed and ethyl acetate as your eluent. Be sure to include loading your sample, eluting your sample, analyzing the fractions, collecting the pure product, and verifying the purity. H▾ E B IA X₂ X² O Ω· Ξ !!! <> 66 X 1. NaBH4, CH3OH 2.

4. The success of each reaction in a Radical Fluorination of an Ibuprofen Derivative is determined by calculating an NMR yield. To do this, one will add 1 equivalent (0.15 mmol) of an internal standard, dibromomethane (CH2B12), to each reaction mixture when one prepare the NMR samples. Look up the molecular weight of dibromoethane and calculate how many mg of dibromomethane one will need to add to each reaction. (Convert 0.15 mmol of dibromometbane to mg.)
The two compounds below are dissolved in ether. Explain how you can use extraction to purify 4-hydroxyindole and 1,6- dichloronaphthalene and explain how would you confirm the purity of your isolated compounds? Include all steps for isolation and purification. Make sure to note structural features that lead your method and explain what each step accomplishes. OH CI 4-hydroxyindole 1,6-dichloronaphthalene As you indicate what you would do, you don't need to worry about amounts. However, here are the reagents available to you (you may not need to use every reagent): ЗМ and 6M NaОН(ag) ЗМ and 6M HClaq) 3M NaCl(aq) Brine Dichloromethane NaCl(s) Ca(OH)2(s) Na,SO4(s)

2) Another method for the above reaction starts with 4-aminophenol hydrochloride (the conjugate acid of 4-aminophenol). The treatment of this the hydrochloride salt with sodium ethanoate (acetate) buffer produces 4-aminophenol which is then able to react with ethanoic anhydride as per our method. i. Why is 4-aminophenol hydrochloride not suitable for direct reaction with ethanoic anhydride? ii. Draw a mechanism (i.e. curly arrows) showing the deprotonation of 4-aminophenol hydrochloride by sodium ethanoate to form 4-aminophenol (the free base).
Find out the volumes required to produce 0.025 mol of the dibenzalacetone (product). Make sure to use 2.2 : 1.0 molar ratio of benzaldehyde and acetone respectively. This is to ensure that benzaldehyde is in excess, and the acetone is the limiting reactant
