Correct order of rate of dehydration of alcohol is :
Options:
Answer:
D
Solution:
Dehydration of alcohols generally follows E1 mechanism (via carbocation).
Rate depends on stability of carbocation formed.
Stability order: 3° > 2° > 1° alcohol.
In (A), substituted cyclohexanol forms more stable carbocation → faster than simple cyclohexanol.
In (B), tert-butanol (3°) reacts faster than ethanol (1°).
In (C), more substituted/fused ring carbocation is more stable → faster than cyclohexanol.
All given comparisons follow correct stability trend.
Final Answer: (D) All of these
