STRUCTURE STUDENT 1/STUDENT 2 HELPING O Add 2 mL oI 15 sodium iodide in acetone into three clean dry test tubes. 4 Add 3 drops oI 1-bromobutane to one vial;4 3 drops oI 2-bromobutane to second vial;4 3 drops oI 2-bromo-2-methylpropane to third vial. 4 $hake and observe closely during the Iirst 15-20 minutes and then at intervals throughout the lab period. 4 ote the time. STUDENT 3/STUDENT 4 HELPING O Add 2 mL oI 0.1M solution oI silver nitrate in absolute ethanol into three dry test tubes 4 Add 2 drops oI 1-bromobutane to one vial;4 2 drops oI 2-bromobutane to second vial;4 2 drops oI 2-bromo-2-methylpropane to third vial. 4 $topper and shake the tubes.Record all observations 4 ote the time. LEAVING GROUP STUDENT 2/STUDENT 1 HELPING O Add 1 mL oI 15 sodium iodide in acetone into two clean dry test tubes. 4 Add 3 drops oI 1-bromobutane into one test 4 add 3 drops oI 1-chlorobutane into the second test tube. 4 $topper and shake the tubes.Observe closely.Record all observations 4 ote the time STUDENT 4/STUDENT 3 HELPING O Add 2 mL oI 0.1M solution oI silver nitrate in absolute ethanol into two clean dry test tubes 4 Add 2 drops oI 2-bromo-2-methylpropane into one test. 4 At same time add 2 drops oI 2-chloro-2-methylpropane into the second test tube. 4 $topper and shake the tubes.Observe closely.Record 4 ote the time STERIC AFFECTS STUDENT 1/STUDENT 2 HELPING O Add 1 mL oI 15 sodium iodide in acetone into three clean dry test tubes. 4 Add 3 drops oI 1-bromobutane into one vial;4 add 3 drops oI 1-bromo-2-methylpropane;4 add 3 drops oI 1-bromo-2,2-dimethylpropane. 4 $topper and shake the tubes.Observe closely.Record 4 ote the time POLARITY OF SOLVENT AFFECTS STUDENT 3/STUDENT 4 HELPING O Add 2 mL oI 0.1M solution oI silver nitrate in absolute ethanol in O VIAL O Add 2 mL oI 0.1M silver nitrate solution in 5 ethanol/95 acetone to a $O VIAL. 4 Ask a neighbor to help you add at the exact same time 1 drop oI 2-chloro-2-methylpropane to each oI the test tubes. 4 $topper and shake.Observe. Record your observations 4 ote the time RATE LAW STUDENT 1 - Hold concentration oI nucleophile constant vary concentration oI alkyl halide O Add 1 mL oI 15 sodium iodide in acetone into two clean dry test tubes. 4 At the same time add 2 drops oI 1.0M 1-bromobutane to one test tube add 2 drops oI 2.0M 1-bromobutane to the other test tube 4 Record observations and time STUDENT 2Hold concentration oI alkyl halide constant vary concentration oI nucleophile O Add 1 mL oI 7.5 sodium iodide in acetone into one clean dry test tube O Add 1 mL oI 15 sodium iodide in acetone into a second clean dry test tube 4 At the same time Add 3 drops oI 1.0M 1-bromobutane to each test tube 4 Record observations and time STUDENT 3Hold concentration oI nucleophile constant vary concentration oI alkyl halide O Add 0.5 mL oI 0.1M 2-chloro-2-methylpropane in ethanol O %o second test tube, add 0.5 mL oI 0.2 M 2-chloro-2-methylpropane in ethanol 4 At the same time, to the vials above, add 1.0mL oI 0.1M silver nitrate solution in ethanol 4 Record observations and time STUDENT 4Hold concentration oI alkyl halide constant and vary concentration oI nucleophile O 1st vial:Add 1.0mL oI 0.1M silver nitrate in ethanol O 2nd vial: Add 0.5 mL oI 0.1M silver nitrate in ethanol, add 0.5 mL absolute ethanol to this vial. 4 %o each oI the vials above at the same time add 1.0 mL oI 0.1 M 2-chloro-2-methylpropane in ethanol
