CHEM 2545 Lecture Notes - Lecture 8: Bromocresol Green, Nucleophile, Sn1 Reaction
Document Summary
Pre-lab 8 homework (35 pts: read through the experimental for lab 8 in your manual (and the handout with the updated experimental volumes) and write out the procedure into your lab notebook, leaving room for observations etc. Please see the bottom of page 69 for an example of an overall reaction. You do not need to designate the reaction duration. (6 pts: why is bromocresol green added to the reactions in lab 8? (4 pts) The color change to yellow demonstrates when the reaction has reached its completion and has reached a ph range between 3. 8-5. 4. When this color change occurs, this is the time to record the time it took for the reaction to reach its completion: what is the nucleophile for all the reactions in lab 8? (4 pts) The nucleophile used for all the reactions in this lab is water.
