Question

Sodium hydroxide can often be used in place of sodium bicarbonate but it emu | be Used in this procedure because of a complicating side reaction. Write a reaction that might occur if NaOH were present. If the reaction is earned out in 80% aqueous ethanol, a new product is formed ka is ethyl I text- pentyl ether. Write a mechanism for its formation. Careful examination of the reaction mixture from question 2 reveals a small amount of another ether, with the formula C_10H_22O. Propose a structure suggest a mechanism for its formation. Rearrangement of the intermediate carbocation in this experiment is not observed Explain why there is no rearrangement. The reaction of text-pentyl alcohol with HNO_3 does not produce. Explain why this reaction fails and predict the structure of the product formed is this reaction Molecular modeling assignment: Construct a butyl carbocation, a 2-butyl carboca tion. and a 2-methyl-2-propyl carbocation, making certain to include a +1charge on each carbocation Show electron density with charge density mapped on top. Determine whether the charge is localized on one carbon or delocalized. Analyze the electron density maps to justify the order of carbocation stability. Calculate the heats of formation of the carbocations, both with and without solvation effects In this experiment, you will investigate the relative reactivity of different types of carbon-hydrogen bonds through free radical halogenation of an alkane. You will synthesize a mixture of chloroalkanes from an alkane via a free radical reaction. analyze the ratios of chloroalkanes via gas chromatography. determine the relative reactivity of primary versus tertiary carbon-hydrogen bonds toward free radical chlorination.

Explanation / Answer

4. Here rearrangement of initial carbocation is not seen because the carbocation formed is tertiary in nature, which is very stable. Rearrangement If any would form less substituted secondary carbocation. Thus no rearrangement of carbocation is seen in this case.
