검증된 단계별 안내1
Identify the type of alcohol for each structure: primary, secondary, or tertiary. Tertiary alcohols generally dehydrate the fastest.
Consider the stability of the carbocation formed during the dehydration process. More substituted carbocations are more stable.
Analyze the first structure: it is a primary alcohol, which forms a primary carbocation, the least stable.
Analyze the second structure: it is a secondary alcohol, which forms a secondary carbocation, more stable than a primary one.
Analyze the third structure: it is a tertiary alcohol, which forms a tertiary carbocation, the most stable, leading to the fastest dehydration rate.
