synthesis 1-Bromobutane Exercises:
3. After the washes described in exercise 2, the 1-bromobutane is treated with anhydrous magnesium sulfate. Why was this done, and what does it remove ?
Homework Answers
The 1-bromobutane is treated with anhydrous magnesium sulfate so as to remove the traces of the water from the 1-bromobutane. Anhydrous magnesium sulfate is a drying agent and removes water from the organic compound.

Experiment 14 SN2: Synthesis of 1-Bromobutane Alkyl halides can be prepared from their corresponding alcohols via an acid catalyzed substitution reaction. The mechanism of these acid catalyzed substitution reactions are labeled as SNI (substitution, nucleophilie, unimolecular) and S2 (substitution, nucleophilie, bimolecular). Tertiary alcohols follow the Syl route, primary alcohols follow the S2, route and secondary alcohols can follow either path. Sth CyHe 81 CH?

LAB REPORT 2- Selected questions from Exercise 3-7 (Acid-fast stain) Note: This is turned in after you have viewed your acid fast stain slides. Bacteria for this exercise are: Mycobacterium smegmatis (or M. phlei) and S. aureus. Q1. Acid fast bacteria are have some significant differences as compared to non-acid fast bacteria. What are the major chemical (structural) differences among these different bacteria that might explain the acid-fast stain? Hint: This structural difference also affects the way the bacteria grow...
