Concept explainers
a)
Interpretation:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how 1-ethylcyclohexanol can be prepared is to be stated.
Concept introduction:
An alicyclic 30 alcohol is to be prepared from benzene. For this purpose benzene has to be converted into an alicyclic
To state:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how to prepare 1-ethylcyclohexanol.
b)
Interpretation:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how 3-methylhexan-1-ol can be prepared is to be given.
Concept introduction:
A six carbon straight chain alcohol with a methyl group on C3 is to be prepared from benzene. By ozonolysis, the benzene ring is broken to get the open chain dialdehyde glyoxal. To one of the aldehydic group in glyoxal, an isopentyl group can be introduced by treating with a suitable Grignard reagent. Upon heating the alcohol will eliminate water to yield an unsaturated
To give:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how to prepare 3-methylhexan-1-ol.
c)
Interpretation:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how 2-methyl-2-phenyl-2 butanol can be prepared is to be given.
Concept introduction:
An
To give:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how to prepare .
d)
Interpretation:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how 5-methylhexan-3-ol can be prepared is to be given.
Concept introduction:
A six carbon straight chain aldehyde with a methyl group on C4 is to be prepared from benzene. By ozonolysis, the benzene ring is broken to get the open chain dialdehyde, maloaldehyde with three carbon atoms. To one of the aldehydic group in the dialdehyde, an isobutyl group can be introduced by treating with a suitable Grignard reagent to get an aldol. The aldehyde group in the aldol is reduced to an alkyl group to get the alcohol requireds.
To give:
Starting with benzene and using other alcohols of six or fewer carbons as the organic reagents how to prepare 3-methylhexan-1-ol.

- Following is the structural formula of the tranquilizer meparfynol (Oblivon). Propose a synthesis for this compound starting with acetylene and a ketone. (Notice the -yn- and -ol in the chemical name of this compound, indicating that it contains alkyne and hydroxyl functional groups.)arrow_forwardThe nitro groups on the benzene ring in the reactant serve two purposes.One is to let you know what atoms in the reactant correspond to what atomsin the product. But what role do the nitro groups play electronically – whywould the reaction be much slower if these nitro groups weren’t attached tothose benzene carbons? Draw any relevant structures to support youranswer.arrow_forwardCCH H20, H2SO4 H9SO4 CH3 Alkynes do not react directly with aqueous acid as do alkenes, but will do so in the presence of mercury(II) sulfate as a Lewis acid catalyst. The reaction occurs with Markovnikov regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called an enol. The enol immediately rearranges to a more stable ketone via tautomerization. Draw curved arrows to show the movement of electrons in this step of the mechanism. Arrow-pushing Instructions Hjö: -CH3 -CH3 H3O*arrow_forward
