Lab #5: Grignard Reaction – Synthesis of Triphenylmethanol John Kang Chem 152L Performed: 7/20/04 Date submitted: ________________ Lab Partners: Sang Lee‚ Vicky Lai TA: John Stanko Abstract: This experiment explored the synthesis of triphenylmethanol through the use of Grignard reagents. The percent yield of the product was 10% on a relatively humid day. The melting point was calculate to be 127.2oC with a literature value of 162oC. An IR spectrum of the product was taken and used

Abstract “Reaction Time” is the interval of time between the application of a stimulus and the detection of a response and has been thought to differ based upon the effects of modality and warning signals. In the “Reaction Time” experiment a total of 24 students from the University of Cincinnati participated in an experiment consisting of two sensory modalities‚ audition and vision‚ which were combined with two levels of warning signal status. The two levels of warning signal status were signal
