Chapter 11.SE, Problem 48AP
Interpretation Introduction

Interpretation:

The reason has to be explained for formation of racemic mixture of 2-bromooctane when the reaction of NaBr with (R)-2-Bromooctane.

Concept introduction:

SN2 reaction:

The alcohol is reaction with acids like hydrochloric acid or hydrobromic acid, the bromine atom attacks back side of the carbon atoms in simultaneous manner and which is bearing alcohol group which yield the corresponding product.

Example:

The tosylated compound is reaction with sodium methoxide which undergoes again type of reaction, the methoxide ion attacks the carbon atom through the back side and provides Inverse configuration of methoxy compound. This is shown below,

Explain this observation: Ethyl 3-phenylpropanoate (C6H5CH2CH2CO2CH2CH3) reacts with electrophiles to afford ortho- and para-disubstituted arenes, but ethyl 3-phenylprop-2-enoate (C6H5CH=CHCO2CH2CH3) reacts with electrophiles to afford meta- disubstituted arenes.
The reaction of (S)-2-bromopentane with potassium cyanide to yield 2-methylpentanenitrile (2-cyanopentane) occurs due to a nucleophilic substitution pathway. The reaction is 100% stereospecific. Please explain what this observation tells about the mechanism of the reaction.
The reaction of butan-2-ol with concentrated aqueous HBr goes with partial racemization, giving more inversion thanretention of configuration. Propose a mechanism that accounts for racemization with excess inversion.(b) Under the same conditions, an optically active sample of trans-2-bromocyclopentanol reacts with concentrated aqueous HBr to give an optically inactive product, (racemic) trans-1,2-dibromocyclopentane. Proposea mechanism to show how this reaction goes with apparently complete retention of configuration, yet withracemization. (Hint: Draw out the mechanism of the reaction of cyclopentene with Br2 in water to give thestarting material, trans-2- bromocyclopentanol. Consider how parts of this mechanism might be involved in thereaction with HBr.)
