Question
Chapter 16, Problem 44DSP
Interpretation Introduction
Interpretation:
The product formed in the given reaction is to be identified.
Concept Introduction:
During pinacol re-arrangement, a
The reaction begins by protonation of one of the hydroxyl groups.
In the next step, the water molecule departs, and an alkyl group from the adjacent carbon atom migrates to its position.
A new carbocation is created, where the hydroxyl group is attached to the carbon bearing the positive charge.
The unshared electrons pair on this hydroxyl group stabilizes the carbocation.
The final step is the formation of a carbonyl group and abstraction of a proton from the oxygen atom.

Grignard reagent is a versatile tool in synthetic organic chemistry. Using bromocyclopentane as a starting material, show how a Grignard reagent, X, is synthesized.
Reaction of X with water produces compound Y while treatment in carbon dioxide followed by hydrolysis forms compound Z. 3-methyl-2butanone reacts with X and hydrolyses to yield compound AA. Draw the structural formulae of compounds Y, Z and AA and write the chemical equations respectively.
When 2-bromo-2-methylbutane is treated with a base, a mixture of 2-methyl-2-butene and 2-methyl-1-
butene is produced. When potassium hydroxide is the base, 2-methyl-1-butene accounts for 45% of the
product mixture. However, when potassium tert-butoxide is the base, 2-methyl-1-butene accounts for
70% of the product mixture. What percent of 2-methyl-1-butene would be in the mixture if potassium
propoxide were the base?

Because bromocyclohexane is a secondary alkyl halide, both cyclohexanol and cyclohexene are formed when the alkyl halide reacts with hydroxide ion. Suggest a method to synthesize cyclohexanol from bromocyclohexane that forms little or no cyclohexene.
