Question

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

Short answer

a. Ethene

b. $2-$methylpropene

c. Cyclohexene

Step-by-step solution

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
