Answer #1

We can use TLC test to show that the obtained product is indeed triphenylmethanol

Perform the TLC test on the product obtained, compare the Rf value of the product with the crude and pure triphenylmethanol, whose value is 0.75, this means that compound produced is triphenylmethanol

Make sure to check the TLC plates for other spots in order to check for the purity of triphenylmethanol

We can also do NMR analysis

since we know the stats that it will have cluster of peaks in the range 1450 to 1600 with the peaks at 3061(presence of phenol)

This is a lab question for the synthesis of triphenylmethanol using a Grignard reaction. "After the Grignard reaction is over, and before you added HCl, you notice some unreacted Mg turnings. What implications will this have on your yield of triphenylmethanol? Is it possible to get a 100% yield if not all the Mg has reacted?"

Draw the structure of the organic product(s) of the Grignard reaction between phosgene (ClCOCl) and excess phenylmagnesium bromide, followed by aqueous workup. You do not have to consider stereochemistry. If a compound is formed more than once, add another sketcher and draw it again. Alternatively, you may use the square brackets tool to add stoichiometries greater than one. Draw one structure per sketcher. Add additional sketchers using the dropdown menu in the bottom right corner. Separate multiple products using the...
