(e) Octane

Short Answer

Expert verified

The conversion of butanoic acid into the following compounds can be explained.

Step by step solution

01

Conversion of butanoic acid into 1-Butanol

The hydrolysis with acids can happen when treated with LiAlH4, there is a reduction of butanoic acid to 1-Butanol. The steps involved are,

CH3CH2CH2CO2H→2.H3O+1.LiAlH4CH3CH2CH2CH2OH

02

Conversion of butanoic acid into 1-Bromobutane

The hydrolysis with acids can happen when treated with LiAlH4, there is a reduction of butanoic acid to 1-Butanol. Treat it with PBr3, there is a conversion of alcohol into 1-bromobutane. The steps involved are,

CH3CH2CH2CO2H→2.H3O+1.LiAlH4CH3CH2CH2CH2OH→PBr3CH3CH2CH2CH2Br

03

Conversion of butanoic acid into Pentanoic acid

The hydrolysis with acids can happen when treated with LiAlH4, there is a reduction of butanoic acid to 1-Butanol. Treat it with PBr3, there is a conversion of alcohol into 1-bromobutane. The butanenitrile hydrolysis with aqueous acids results in pentanoic acid formation. The steps involved are,

CH3CH2CH2CO2H→2.H3O+1.LiAlH4CH3CH2CH2CH2OH→PBr3CH3CH2CH2CH2Br→2.H3O+1.NaCNCH3CH2CH2CH2CO2H

04

Conversion of butanoic acid into 1-Butene

The hydrolysis with acids can happen when treated with LiAlH4, there is a reduction of butanoic acid to 1-Butanol. Treat it with PBr3, there is a conversion of alcohol into 1-bromobutane. Treatment of 1-bromobutane with KOH, eliminates HBr to get 1-butene. The steps involved are,

CH3CH2CH2CO2H→2.H3O+1.LiAlH4CH3CH2CH2CH2OH→PBr3CH3CH2CH2CH2Br→alcoholic KOHCH3CH2CH=CH2

05

Conversion of butanoic acid into Octane

The hydrolysis with acids can happen when treated with LiAlH4, there is a reduction of butanoic acid to 1-Butanol. Treat it with PBr3, there is a conversion of alcohol into 1-bromobutane. The conversion of 1-bromobutane into lithium-dibutyl copper in addition to octane. The steps involved are,

CH3CH2CH2CO2H→2.H3O+1.LiAlH4CH3CH2CH2CH2OH→PBr3CH3CH2CH2CH2Br→2Li2CH3CH2CH2CH2-Li+→Cul(CH3CH2CH2CH2)2Cu-Li++CH3CH2CH2CH2Br→CH3(CH2)6CH3
