The ease of dehydration of alcohols to produce alkenes of the order
Correct answer: A. Tertiary > Secondary > Primary
- A. Tertiary > Secondary > Primary
- B. Primary > Secondary > Tertiary
- C. Secondary < Primary < Tertiary
- D. Tertiary < Secondary < Primary
Explanation
The ease of dehydration of alcohols to produce alkenes is directly related to the number of beta-carbon atoms in the alcohol. Tertiary alcohols have the highest ease of dehydration due to having 3 beta-carbon atoms, followed by secondary alcohols with 2 beta-carbon atoms, and finally primary alcohols with 1 beta-carbon atom. The size of the R group in the alcohol also affects the ease of dehydration. Therefore, the correct order is Tertiary > Secondary > Primary. The other options are incorrect as they do not consider the number of beta-carbon atoms in the alcohols.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
