A student attempted to prepare 1-chlorobutane by treating 1-butanol with a solution of NaCl. Did the student get the desired product? Explain.
Homework Answers
No, Student will not get desired product because NaCl is a salt of strong acid and a strong base. Here, to ptepare 1-chlorobutane from alcohol we have to proceed via neucleophilic substitution reaction so to occur we need a very strong electon deficient species to attack on Oxygen of atom and can create carbocation. Hee NaCl has electron deficient specy Na+ ion but it is stable salt which can not cause substitution.

A graduate student attempted to make 1-methyl-1-cyclopentene by
the elimination of HBr from 1-bromo-1-methylcyclopentane. The
reaction was done by heating 1-bromo-1-methylcyclopentane in
methanol. The student received a low yield of the desired
1-methyl-1-cyclopentene. Why do you think the yield was low? What
could be done to improve the yield?

how many millimeters of a 90.0% (w/v) NaCl solution will you need to prepare 500mL of a 0.225% NaCl solution? What amount of NaCl (MW 58.44) in grand must be combined with water to prepare 1000mL of a 0.90% (w/v) normal saline solution? What amount of NaHCO3 (MW 88.01) in grams is needed to prepare 5000mL of 0.024 M solution? Please explain - thank you!

12. A student added one equivalent of 3,4-epoxy-4-methylcyclohexanol to a solution of methylmagnesium bromide in diethyl ether, and then added dilute hydrochloric acid. He expected that the product would be 1,2-dimethylcyclohexane-1,4-diol. He did not get this expected product. Draw the structures of 3,4-epoxy-4-methylcyclohexanol, methylmagnesium bromide, and 1,2- dimethylcyclohexane-1,4-diol. Explain why the student did not get his expected product. What organic product(s) did he get? Show all reaction steps for better yet, show the reaction mechanisms). CH, MgBr CH4 att HOH

1. You prepare a NaCl solution by dissolving making 250mL solution out of 0.1409 g of NaCl (MW = 58.443 g/mol). You use this solution to standardize a Hg(NO3)2 solution. The volume of Hg(NO3)2 needed to titrate 10 mL of NaCl is 4.017 mL what is the molarity of the a Hg(NO3)2 solution? Note: Hg2+ + 2 Cl → HgCl2 2. Using the Folin-Wu tungstic acid method you pipet 10 mL of a serum sample and precipitate the protein (Note:...

A student was planning to synthesize 2-chloro-3-methylbutane from 3-methyl-2-butanol using concentrated HCl, similar to the reaction you did. When the experiment was carried out, the product isolated was 2-chloro-2-methylbutane. Explain these results by showing a plausible mechanism for the formation of 2-chloro-2-methylbutane under these reaction conditions. (Hint: it is an SN1 reaction, but think about what can happen to the carbocation intermediate that we learned about in lecture to cause that product to form.)
