Question:
Which one among the following compounds will most readily be dehydrated under acidic condition?
Which one among the following compounds will most readily be dehydrated under acidic condition?
Show Hint
Acidic dehydration trend:
\[ 3^\circ > 2^\circ > 1^\circ \]
More stable carbocation \( \Rightarrow \) faster elimination.
\[ 3^\circ > 2^\circ > 1^\circ \]
More stable carbocation \( \Rightarrow \) faster elimination.

- Option a
- Option b
- Option c
- Option d
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Concept:
Ease of dehydration depends on:
Tertiary alcohol dehydrates most easily.
Ease of dehydration depends on:
- Stability of carbocation formed
- Tertiary > Secondary > Primary
- Primary alcohol (A): difficult dehydration
- Alpha or beta hydroxy ketones: less favorable
- Tertiary alcohol (D): forms stable 3° carbocation
Tertiary alcohol dehydrates most easily.
