STANDARD Chemistry Dehydration of Alcohols MCQ Question
Which of the following alcohols on dehydration gives most stable carbocation?
CH₃ − CH − CH₂OH | CH₃
Image of a complex structure
CH₃ − CH₂ − CH₂ − CH₂OH
CH₃ − CH − CH₂CH₃ | OH
Correct Answer
Detailed Explanation
The most stable carbocation is formed from the alcohol that can form a tertiary carbocation upon dehydration. In this case, the structure in option A forms a tertiary carbocation, which is more stable due to hyperconjugation and inductive effects.
