Solution
Solution Steps
Step 1: Identifying the type of alcohol
Dehydration of alcohols occurs most readily with tertiary alcohols, followed by secondary alcohols, and then primary alcohols. This is due to the stability of the carbocation intermediate formed during the reaction. More substituted carbocations are more stable.
Step 2: Classifying each alcohol
A is a primary alcohol.
B is a secondary alcohol.
C is a tertiary alcohol.
D is a primary alcohol.
E is a secondary alcohol.
Step 3: Determining the most readily dehydrating alcohol
Since tertiary alcohols dehydrate most readily, the answer is C.
