Question

Lab Section Name Write-Up Sheet for Multi-step Synthesis Experiment (Day 2) Give the reaction scheme (starting material(s), reagents, ex heme (starting material(s), reagents, expected product) for the second step of your multi- step synthesis. Solvents and catalysts should be included though work up steps need not be shown. O Tethanolo 2-(Phenylamino) phano DATA & ANALYSIS N - Playl-2-hylony beneylumine Amounts of Starting Materials and Reagents Used List all starting materials and reagents used in the second step of your multi-step synthesis (solvents and catalysts need not be indicated). For starting materials and pure reagents, give the measured weight actually used as well as the number of moles. Por reagents used as solutions, give the measured volume used, the concentration of the solution, and the number of moles. Melting Point Data Literature melting point of organic starting material: 41-$3°C Source: chemoub Literature melting point of 2 starting material or reagent: (not all reactions will have a second solid starting material or reagent) Source: Chemoub Literature melting point of intended product: 125 121 Source: Experimental melting point of product obtained: 125-127°C (If no solid product obtained, check here): Percent Yield Give both the weight and the percent yield of the product obtained and show your calculations. If no product was obtained, check here and show calculation of percent yield if 0.20 g of product had been obtained 0.959 0.939 3x100 - 80.87 ~(81) methicalxl Starting weight; 1.149. 11.14 213.56g) = 115 Assessment Was the desired product obtained? Briefly explain why you believe the product was or was not obtained. Also, explain how you could determine by means of either IR or 'H NMR spectroscopy whether or not your reaction was a success Describe at least one specific peak (or set of peaks) that would be present in the product but not the starting material(s) OF vice versa. For example, if your reaction was the nitration of benzene to give nitrobenzene, you might say, "The product would have two large peaks at 1350 cm and 1550 cm in its IR spectrum that wouldn't be present in the starting material" (Use the back of this page for your answers to these questions).

I just need help with the assessment section

Answer 1

Assessment

your expected product is

НО.. HNT

your percent yield is good enough to say yes the product was obtained..using ir and nmr you can easily differentiate between starting material and product

using IR (major difference)

starting material has C=N group which have stretching frequency is near to 2240-2260 cm^-1

and product has N-H bond which have stretching frequency near to 3300-3400 cm^-1

using NMR

starting material has C=N group which have no chemical shift due to no proton

product have Ar-NH group which have chemical shift near to 3-4 ppm

so easily you can isolate product and starting material.

NOTE( i am using starting material and product here which you are providing )
