Lab #6: Preparation of 4-Bromo-2-Chloro-6-IodoBenzene Purpose: To complete the sixth and final step in our continuing, multi-step organic reaction. We will use the sample of the substance we created in last week’s lab experiment, 4-Bromo-2-Chloro-6-IodoAniline and further react it to form a new substance, 4-Bromo-2-Chloro-6-IodoBenzene. Reaction: Data: Mass of 4-bromo-2-chloro-6-iodoaniline g Mass of powdered sodium nitrite g Volume of absolute ethanol added to initial sample mL Volume of concentrated sulfuric acid added dropwise mL Volume of water added to flask before steam distillation mL Volume of dichloromethane washes used mL Crude weight g Sample weight g Melting Point of final sample °- ° Procedure: My lab partner began this week’s experiment by measuring out our sample from last week. We then proceeded to use the ratio of our sample, g, to the 2 grams the book asks you to use, to figure out the correct amounts to use for all the other materials needed in the experiment. We first took our sample of
