Q. 12.28 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw the condensed structural or line-angle formula for the alkene produced by each of the following dehydration reactions: 

Step-by-Step Solution

Answer

a. Ethene  

b. $2-$methylpropene

 

c. Cyclohexene  

Part(a) Step 1: Given information

We need to draw the condensed structural or line-angle formula for the alkene produced by the following dehydration reaction 

${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{OH}\stackrel{{\mathrm{H}}^{+},\mathrm{heat}}{\to }$

Part(a) Step 2: Explanation

The reaction in which alcohol combines with protic acid to lose water molecules and generate alkenes is known as dehydration of alcohol.  

Dehydration of Ethane$-1-$ol  gives Ethene

 

Part(b) Step 1: Given information

We need to draw the condensed structural or line-angle formula for the alkene produced by the following dehydration reaction 

${\mathrm{CH}}_3-\mathrm{CH}\left({\mathrm{CH}}_3\right)-{\mathrm{CH}}_2-\mathrm{OH}\stackrel{{\mathrm{H}}^{+},\mathrm{heat}}{\to }$

Part(b) Step 2: Explanation

The reaction in which alcohol combines with protic acid to lose water molecules and generate alkenes is known as dehydration of alcohol.  

Dehydration of $2-$methyl-propane$-1-$ol gives $2-$methyl-propene.

Part(c) Step 1: Given information

We need to draw the condensed structural or line-angle formula for the alkene produced by the following dehydration reaction 

Part(c) Step 2: Explanation

The reaction in which alcohol combines with protic acid to lose water molecules and generate alkenes is known as dehydration of alcohol.  

Dehydration of Cyclohexanol gives Cyclohexene
