Draw molecular structures of bromobenzene, benzophenone, and triphenylmethanol and biphenyl in the order of increasing polarity...
1. a) Why does biphenyl have a higher Rf value than either benzophenone or triphenylmethanol? Explain based on the structures and their effect on mobility in the TLC process. b) Which compound, benzophenone or triphenylmethanol has a higher Rf value? Explain, based on their structures, how you can predict this. c) You developed your TLC using a 10% mixture of diethyl ether in petroleum ether. Petroleum ether is a mixture of non-polar alkanes, so this TLC solvent is composed of...
Draw the mechanism for this reaction. 1) Mg, Et20 2) bromobenzene triphenylmethanol benzophenone 3) H2O
Rank the following compounds [Benzophenone, Malonic Acid, and Biphenyl] from least polar to most polar, and how does the polarity of a solute affect its ability to dissolve in a polar or non polar solvent?
Use your textbook or an appropriate reference to determine the structural formulas of biphenyl, benzhydrol, and benzophenone. (a) Draw the structural formulas of these compounds. (b) Based on these structures, list the three compounds in order of increasing polarity.

In Grignard reaction:
1) The main by-product of the reaction to
prepare triphenylmethanol is biphenyl. Draw the structure of
biphenyl and write a reaction to explain its formation.
2) Another typical
by-product of any reaction using phenylmagnesium bromide is
benzene. Write a reaction to explain its formation.

Grignard Reaction with a Ketone: Triphenylmethanol Introduction: The purpose of this lab is to prepare phenylmagnesium bromide, a Grignard reagent, and react it with benzophenone to give triphenylmethanol. Grignard reagents are very reactive and must be synthesized in an environment free of water or any other source of potential proton donor. Once made, the Grignard reagent will do a nucleophilic attack on the carbonyl carbon of the ketone, benzophenone. The result is an alkoxide that is then protonated to give...
