JEE Main Chemistry question
A number is assigned to each of the following alcohols: (1) 1-phenylbutan-1-ol (2) 1-phenylbutan-2-ol (3) 2-phenylbutan-1-ol (4) 2-phenylbutan-2-ol. Which numbered molecule would undergo dehydration most easily?
Answer: 4
Solution
Acid-catalysed dehydration proceeds through the most stable accessible carbocation; molecule (4), 2-phenylbutan-2-ol, ionises to a carbocation that is both tertiary and benzylic, gaining
