Dong Hyun Suh Mr. Erdei CHE2204 March 2, 2009 Post-Laboratory Report Grignard Reaction With a Ketone: Triphenylmethanol Data: Product: 0.1382 g Published Melting point: 166 C Experimental Melting point : 159 C Calculations: Theoretical yield calculation Results/Conclusion: The high product mass was expected since the Grignard reaction is responsible for forming new carbon-carbon bond. The final product has molar mass of 260.33g/mol. Simple stoichiometry does not give us a proper theoretical mass calculation since it goes through at least 3 intermediate steps with different reagents. However, I felt that this

Unformatted text preview: experiment was very difficult in microscale since it was very hard to follow though with the procedure. That’s the reason why we used the double amount of everything to have the experiment work better. Also, it was very interesting to see this experiment working in real-life after learning the theory in lectures. Also, the melting point test for the product indicates that a near pure substance was made through the reactions....
