A chemist combines 3-bromoheptane and sodium methoxide in a polar aprotic solvent? What type of reaction is likely to occur? Hint: use the figure below to help guide your decision.
Homework Answers
3-BROMO HEPTANE ON REACTION WITH SODIUM METHOXIDE IN POLAR APROTIC SOLVENT UNDERGOES SN2 REACTION BECAUSE Polar aprotic solvents tend to favor substitution (SN2) relative to elimination (E2) BUT IF If the solvent is polar protic, the reaction will likely be E2. HERE SOLVENT IS POLAR APROTIC THUS REACTION TAKING PLACE IS A SN2 SUBSTITUTION REACTION .

Sodium Cyanide reacts with 2-bromobutane in dimethylsulfoxide to form a substitution product. Identify the configuration of the 2-bromobutane structure shown below. Then draw the substitution product formed when this enantiomer reacts with NaCN in DMSO, and indicate the stereochemistry of the product. O O (R)-2-bromobutane (S)-2-bromobutane Use wedge-and-dash bonds to show stereochemistry, and show explicitly the hydrogen...

3. If sodium methoxide in methanol was used in place of potassium t butanol, your GC analysis would look much more like the 2-butanol/sulfuric acid reaction products. In addition, a new, non-alkene product would be present in the GC analysis from a competing, non-elimination mechanism. Explain why the alkene distribution would change, what the new product would be, and why this new product would form. 4. If 2-bromobutane was reacted with trimethylamine to produce sec-butyl trimethyl- ammonium bromide (see below),...

Question 28 1 pts Imagine that a scientist mixes bromoethane and sodium tert-butoxide in 2-methyl-2-propanol. What type of reaction is likely to predominate? Remember to consider the type of alkyl halide that is involved, and remember also to consider whether the anion will act predominantly as a base or as a nucleophile or as both a base and a nucleophile. If the latter, consider the figure below to guide your decision. Finally, remember to consider the Apka rule, as it...

the
bilayer or to move 50 Å in a transverse direction (through the
bilayer) from one leaflet to another? Why?
