D
Text Solution
Verified by ExpertsThe correct answer is:
B
Alcohols undergo dehydration to form alkene on treating with a protic acid (Ex. Conc
or 
or Catalyst such as Anhy. Zn Cl 2 ). 
and 
alcohols are dehydrated under milder conditions. During this process carbocation intermediate is formed and we know that stability of carbocation follows the order- 
Therefore, tertiary butyl alcohol forms stable carbocation or carbonium ion on dehydration.
